uhf vs vhf range

Very High Frequency (VHF) range is from 30 MHz to 300 MHz. Yaesu FT-8900R Quad Band Hi Power FM Amateur Ham Radio Transceiver. It's because of the difference between how VHF vs UHF signals react around structures. The monthly service contract is obtained through the radio dealer. Compare that to a handheld two-way radio which uses between 1/2 - 5 watts. As you can see, UHF is better at navigating through the smaller spaces within a building to reach it's destination. Now that you know more about the advantages and disadvantages of using VHF or UHF radio frequencies, you should have no trouble finding the right set that can meet your needs. There are some tips and tricks you can try if you find yourself in a situation in which you need to get more range out of your walkie talkie. So mount your antenna as high-up on your vehicle as possible. UHF vs VHF Microphones. In the US and Canada, the VHF television band occupies frequencies between 54 and 216 MHz and the UHF band between 470 and 890 MHz. The two frequency ranges (also called "frequency bands") used in most two-way radios are VHF (Very High Frequency), and UHF (Ultra High Frequency). VHF & UHF frequency waves VHF walkie talkies. globally and in back-country areas where most other forms of communication are not available. In general, VHF channels are numbered 2 to 13 and UHF channels 14 to 51. Unlike frequencies below 2MHz, radio waves in these higher frequencies travel in straight lines (called "line-of-sight" signals), and generally cannot travel beyond the horizon. Their peaks and troughs propagate more closely together. They differ in how they travel, and how they react when they encounter materials. VHF signals are often blocked by metal within the building. Range capability is the biggest factor for most buyers. However, if a VHF wave and a UHF wave were transmitted over an area without barriers, the VHF wave would travel almost twice as far. These bands are frequently used by maritime, military, emergency, and air traffic control systems. VHF features 130-174 megahertz, while UHF features 400-520-megahertz. radios from one office can talk to the other locations, even if these offices are thousands of miles apart. The metal mesh keeps the microwaves from passing outside the oven. Both ships have the same 25-watt radio, the difference in this example is the height of the antenna. The range from 174 to 216 MHz is used for channels 7 through 13 … However, radio signals are able to travel through many types of non-metallic objects including furniture, human bodies, masonry, and drywall. Outdated browsers have security issues and don't follow new web standards. Basically, when it comes to VHF vs UHF range, it’s often a trade-off. *Single side band (SSB) is used in some amateur (ham) When looking at your TV and the channels, the UHF channels will usually be numbered higher. Many wireless systems use a process called companding that compresses the transmitted audio signal at the microphone then expands it at the receiver to restore the dynamic range of the audio. VHF = "Very High Frequency". Save my name, email, and website in this browser for the next time I comment. Assume you are trying to communicate from one side of a commercial building to the other. such as gas and oil exploration, back-country search and rescue operations, or other other companies needing global communications in Unfortunately, VHF signals are usually blocked by the metal inside the building. The lowest high band often includes eight frequencies that are designated by the FCC. Although microwaves are small, they are still bigger than the tiny holes in the metal mesh. VHF waves are not very good at penetrating walls, buildings and "Why?" implement. However, stubby antennas can reduce your range by up to 30% over a whip antenna. The key considerations that affect range are: signal type, antenna, obstructions, and signal strength (wattage). Even though VHF can pass through obstacles better and travel farther, that doesn’t mean it's always the better choice. Both UHF and VHF have been used over the years for radio and television transmissions, with individual stations assigned specific broadcast ranges along the … Also, the denser an object, the more it reduces the signal strength. In fact, when trying to increase your range, increasing your antenna height is a more effective way to extend your range than increasing your power, you get more bang for your buck (so to speak). However, a VHF signal is reflected because it’s significantly wider than a doorway. There is a “but”, VHF is not very good for going through walls or structures. Distance calculation is based on the antenna’s height. However, low frequencies are very vulnerable to other issues. Posted by 1 year ago. However, their signal can still only travel to the horizon. These radio waves are significantly shorter compared to VHF, which is why the antenna length is often reduced as well. HAM frequencies and CB radio frequencies are in the high frequency range of twenty-nine to fifty-four megahertz, which gives them some of these qualities. VHF radios offer a larger broadcast range, using radio waves from 30 MHz to 300 MHz. When it comes to the distance to the horizon being the max communication range, an antenna will be a key factor. Another important factor in determining the distance a radio can communicate is it's signal strength. In some cases, using VHF will be a better choice, while in others, UHF will be the smarter decision. However, VHF radio has weaker building penetration strength compared with UHF. High-band VHF ranges are a better choice for pro use compared to low band. With GMRS, you’ll get up to five watts. However. So how far can you really expect to talk? VHF Vs. UHF Range: Best Choices for Indoor and Outdoor Use, 2021 Best Walkie Talkies : A Buyer’s Guide, Best Long Range Walkie Talkie Reviews and Comparisons of Top Selling Models, Waterproof Walkie-Talkie for the Ultimate Adventure, Best Bluetooth Speaker for On the Go and Home Use: Buyer’s Guide for 2021 and Best-Sellers, Best Police Scanner Base and Handheld Scanners: 2021 Buyer’s Guide. Very high frequency (VHF) signals are transmitted from 54 to 216 megahertz (MHz), while ultra high frequency (UHF), as the name implies, comes through much higher, 470 to 806 MHz. IP radios require a controller, which Archived. In this guide, I’ll go over how VHF and UHF frequencies work and what can have a negative impact on a two-way radio’s range. UHF and VHF frequencies are part of the overall electromagnetic spectrum. Well in reality, what they are saying, is "if the horizon is not a factor, say you are on top of a mountain, and there are no obstructions (clear line-of-sight), then there is enough signal strength for the signal to carry for 36 miles. Other types of handheld radios such as HAM and GRMS are limited to five watts. A VHF signal is able to penetrate objects easily, unlike UHF. Raising the receiving antenna's height would extend the line-of-site even more. UHF is also the better choice in urban areas with a lot of houses and commercial buildings that the radio signal will be passing thru. Many FRS/GMRS radios on the market today have a stubby antenna because it's easier to put your radio in a backpack or pocket. If you are using the radio primarily outdoors with clear line-of-sight, then VHF is a better choice because it's signal will travel farther. When we said "the distance to the horizon is the maximum communication range" we didn't mention one key factor, your antenna. For now, let's just leave it at a simple rule-of-thumb: a 6ft high antenna at both ends of the transmission (transmit & receive), will have a maximum range of approximately 6 miles. Expect Note: Range and coverage are estimates and are not guaranteed." How can they make such a claim? Communication distance can be somewhat improved (25%to 50% further) over this on VHF and UHF by the use of a gain antenna.The distance can be adversely affected by interference from the vehicle engine; further distance can be achieved by parking on a hilltop or open area and shutting off … Most companies already have IT departments, which will readily understand these products. One last thing we didn't mention is the weather, and other atmospheric conditions can affect radio transmissions. But since there isn't much you can do about mother nature, we will only give it a passing mention here. To sum it up, the higher your antenna the longer your communication range. Unfortunately, there are lots of variables involved, and so there is no easy and specific answer. Radio waves generally won't pass through it. Microwaves are extremely high frequency with small signal waves. Like the VHF region, the UHF region contains several bands that are used for wireless microphone systems. Thus, two people carrying a handheld two-way radio, the maximum communication distance on flat ground with no obstructions is approximately 6 miles. "Why?" A radio signal is weaker with a low battery. The calculation of distances is based on the height of your antenna. This can even allow you to communicate across the A UHF station with a 60-mile coverage radius requires transmitting at 3,000,000 watts. Network radios (also called Radio-Over-IP, RoIP, IP or WALN) radios communicate through the internet via a wireless internet UHF television broadcasting is the use of ultra high frequency (UHF) radio for over-the-air transmission of television signals.UHF frequencies are used for both analog and digital television broadcasts. If a VHF wave and a UHF wave were transmitted over an area without barriers, the VHF wave would travel almost twice as far. UHF, or ultra high frequency, relates to the band that covers the range between 300 megahertz or MHz and 3000MHz. VHF- Very high frequency (from 30 MHz to 300 MHz) Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). It’s pretty common to come across advertisements for two-way radios that claim a model has a range of thirty miles or more. But it doesn't end here, there are other considerations we need to explain. For any given antenna height use this formula: Horizon at Ground Level (in kilometers) = 3.569 multiply by the square root of the Antenna Height (in meters). So if the antenna height is at 6 feet tall (1.82880 meters), times the horizon (3.569), equals 4.83 kilometers, or 2.99 miles away. BUT, radio signals can travel through many non-metallic objects such as drywall, masonry, human bodies, furniture, and many other objects. UHF channels are typically given higher channel numbers, like the US arrangement with VHF channels 2 to 13, and UHF channels numbered 14 to 83. Frequencies below 2MHz (Megahertz) are reflected off the atmosphere, thus they can follow the Earth's curvature. When we said "the distance to the horizon is the maximum communication range" we didn't mention one key factor, your antenna. Commercial antennas typically indicate the range at which they can capture a signal. You’ll find different bands within this frequency, such as high and low-bands. What is VHF? This is done to deal with the limited capacity of wireless channels. Indoor coverage at VHF is approximately 270,000 sq ft and 300,000 sq ft at UHF. VHF radios can also be purchased with a range of extra safety features including GPS and Digital Selective Calling (DSC) to further boost safety onboard your vessel. Even though VHF can pass through obstacles better and travel farther, that doesn’t mean it's always the better choice. UHF = "Ultra High Frequency." UHF is the better all around signal and is by far the most popular, so if you are in doubt, choose UHF. Although VHF (Very High Frequency) and UHF (Ultra High Frequency) are both used to describe frequencies, these are not related to the frequency of the voice that is being recorded. When you require a walkie talkie for long range that is used in Australia for predominately outside operations, such as mines or taxis services, VHF (Very High Frequency) is much better. UHF television refers to the use of ultra high frequency radio to broadcast to your television set. Antennas on boats are much the same. VHF, or very high frequency, operates at a lower level, covering the frequency range from 30 MHz to 300MHz. Remember, UHF signals are shorter than VHF, this is important when you're in or around buildings. Other Examples: They differ in how they travel, and how they react when they encounter materials. Perfect for those looking for the longest range possible and easy setup, such as companies operating vehicle fleets in large metropolitan areas. Installed in vehicles, they run off the vehicle's battery. obstructions the range is approximately 4+ miles. UHF vs VHF Radios. UHF (ultra high frequency) signals operate at the higher end of the radio frequency spectrum. You can get radios that use either UHF (Ultra High Frequency) or VHF (Very High Frequency). You can get radios that use either UHF (Ultra High Frequency) or VHF (Very High Frequency). These radio waves will usually only go as far as line of sight. Common uses for VHF are FM radio broadcasting, television broadcasting, two way land mobile radio systems (emergency, business, private use and military), long range data communication up to … Close. Moreover, handheld radios run off a small battery, so a higher wattage would mean your batteries will not last very long. VHF – Very High Frequency. Radio waves can not pass through metal. We are often asked "Is VHF or UHF better?" The advantage of VHF radio is that it can cover more distance with less power due to VHF waves are longer and remain closer to the ground. A VHF radio is effective for communication of up to approximately 20 nautical miles, allowing for a greater range. The calculation of distances is based on the height of your antenna. It is a bit misleading as they usually specify the distance for Ultra High Frequency (UHF). Default sorting is by 3rd order Dynamic Range (wide spaced). Additionally, hilly terrain can also be your enemy. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). Aviation radios in the air have the most advantage, no obstacles and you're already very high! country. Television broadcast and FM radio broadcast (usually utilizes the 88MHz – 108MHz range) are two major uses of VHF. Remember, UHF signals are shorter than VHF, this is important when you're in or around buildings. The UHF wavelength is roughly one and a half feet wide, the VHF wavelength is roughly five feet wide. With a direct ‘Line of Sight’ between, say, 2 radios on two mountain-tops either VHF or UHF signals will go a very long distance…. As I mentioned above, UHF and VHF are the two most commonly used radio signals. The maximum wattage for each radio type is set by the FCC. However, there are additional factors to consider. If you’re looking for a set of walkie talkies that you’ll use mainly outdoors where you’ll have a clear line of sight, then a set that operates on VHF will be a great choice since the signal will be able to travel farther. The ac current and … June 20, 2018. The stronger the signal strength, the more it can withstand weakening when it passes through obstacles. If range is a priority for you, then look for walkie talkies that are equipped with whip antennas. The differences between UHF and VHF Radios UHF. The UHF signal (1 1/2 ft) passes through the door easily. Now, technically when comparing signals between CB vs VHF radios, the later wins by a longshot. If both waves were transmitted over a stretch of land that had no obstacles, VHF would still be able to travel twice as far. It's because of the difference between how VHF vs UHF signals react around structures. Radio waves generally won't pass through metal or hills at all. Also, mount your antenna in a straight-up position, not at an angle. For most people who are new to walkie talkie use, the choice is more complicated since most people simply don’t know the differences between VHF and UHF, which often leads to them choosing the wrong type of system for their situation. To highlight the differences in indoor range, below is an excerpt from a brochure of a leading two-way radio maker on the predicted range of one of their lines of handheld VHF and UHF two-way radios: "Coverage estimates: At full power, line-of-sight, no obstructions the range is approximately 4+ miles. The stronger a signal, the more it will be able to withstand the weakening when it passes through an object or an obstacle. devices and other transceiver units. A user who is around six feet tall and is using a five-watt walkie talkie on flat terrain will have a max range of six miles. General. VHF vs. UHF – Why OTA Frequency Bands Matter for Cord Cutters with Antennas. A higher range of fifty-four megahertz will operate TV channels and certain types of wireless systems. As a general rule, the lower the frequency, the greater distance it can travel. Essentially, the trade-off that you’ll be making is the longer distance VHF offers versus avoiding any potential dead spots around or in structures, which is what UHF signals will help you avoid. The difference between these two signals is how they react around structures. However, if you’re planning on using the walkie talkies around or in buildings, in heavily wooded areas, or in urban areas, than a set that operates on UHF is the better choice here since the signal will easily navigate around structures and will not be blocked like VHF signals will be. Lets deal with VHF vs UHF first; There are two main issues to consider. Feel free to search, filter or sort as you wish. The distance to the horizon is the maximum communication range for most two-way radios. The most common question people ask when they go to the market to buy a two-way radio intercom is how far they can communicate? you ask. But in terms of VHF vs UHF range, which type of radio frequency truly offers the type of range most buyers are looking for? However, while VHF can easily pass through obstacles farther and easily, it doesn’t always make this type of signal the best choice. monthly fee per radio. Additionally, the denser an object, the more it will reduce the strength of the radio signal, meaning with every object the signal passes through, the range will be shortened. However, each time a radio signal passes through an object the signal strength is reduced. Satellite radios communicate through an array of satellites know as the Iridium satellite constellation. you ask. VHF, or very high frequency, operates at a lower level, covering the frequency range from 30 MHz to … First, not all radio signals are the same. Anything that’s in the way of the line of sight can have a negative impact on frequency range including tall trees. We are often asked "Is VHF or UHF better?" If you search for reviews on these same radios, you will find many disappointed people saying they can't get anywhere close to the advertised range. One of the easiest ways to extend your range is by focusing on your antenna. Please update your browser to fully experience this website. But keep reading, there are other things to consider as well, such as power and obstructions. Always make sure your battery is fully charged. Both UHF and VHF radios are prone to line of sight factors, but VHF a little more so. If you are using the radio in or around buildings, in urban areas, or heavily wooded areas, then UHF is a better choice because it's signal will navigate around obstacles better. These higher frequencies can travel in straight lines that are called line of sight signals, unlike frequencies that are below two megahertz. the spectrum bands 410 MHz to 450 MHz (UHF Band 1) and 450 MHz to 470 MHz (UHF Band 2) can meet the future needs of existing and new users and applications. One of the best ways to increase range is to increase your height. In other words, the exact distance to the horizon varies depending on your antenna height. Not every antenna on a walkie talkie is the same. Aviation radios in the air have the most advantage, no obstacles and you're already very high! But does this mean the users are guaranteed six miles? This makes VHF easier to broadcast over a long range. Microphones are used to capture sound, whether its from the human voice, animals, or even from the environment, and either amplify it for rebroadcast or to record it for later use. UHF is a better choice if you’re looking for a system for indoor use or in urban environments. These repeaters typically have about 50 watts of power, extending the reach to about 50 miles of coverage. Low-band usually overlaps with high-band UHF. Antenna Height                     1.82880 meters (6 feet off the ground)Horizon at Ground Level       x 3.569   kilometersAntenna Horizon                    4.83    kilometers (or 2.99 miles) away Remember at the beginning we discussed the claims some radio brands make of "up to 36 miles" or more communication range? Scroll to the bottom for notes. UHF offers a better all-around signal and is the more popular option, due to its versatility. This is because theVHF signal waves can travel a … Unlicensed radios such as: FRS radios are limited to 2 watts, MURS 2 watts, CB radios 4 watts, and CB radios with SSB channels can have 12 watts on the SSB channels*. For mounted antennas, it's important to mount your antenna on the highest point possible. To sum it up, the more watts a radio has, the stronger the signal. However, if a VHF wave and a UHF wave were transmitted over an area without barriers, the VHF wave would travel almost twice as far. The signal strength is basically a result of a walkie talkie’s power output, measured in watts. The FCC has limited FRS channels to just a couple of watts. No single factor is a silver-bullet to extend your communication range. At that frequency, the effects of the capacitor and inductor cancel. A stronger signal is capable of withstanding successive passes through obstacles, allowing it to travel farther. No. VHF, or “very high frequency” radio bands are between 30-300MHz. The transmission is high enough that it can penetrate through walls, which is what makes it a better choice for indoor use. Models that run on a higher wattage mean a walkie talkie’s batteries will not last very long. Their signal is much stronger than a handheld radio, therefore less affected by obstacles. VHF vs UHF – Real World Applications But marine radios have a big advantage, there are no obstacles on the open water! The simplest answer is: Go with VHF if you’re planning on using your walkie talkies outside and in areas that are relatively free of major obstructions, such as buildings. you say. satellites (and 9 spares in space) used for worldwide voice and data communication from hand-held satellite If you search for reviews on these same radios, you will find many disappointed people saying they can't get anywhere close to the advertised range. UHF and VHF are the two most commonly used frequency ranges for walkie talkies. However, the VHF signal is reflected since it is wider than the door. CB radios, and some HAM frequencies, are in the HF (High Frequency) range of 29-54MHz, giving them some of these qualities. channels. A typical VHF station operates at about 100,000 watts and has a coverage radius range of about 60 miles. You can see there is a big difference. A radio wave is not able to pass through metal. For any given antenna height use this formula: Horizon at Ground Level (in kilometers) = 3.569 multiply by the square root of the Antenna Height (in meters). IP radios work well for businesses wanting to communicate within locations covered by their computer network. advantage, or disadvantage, of LTE is your radios work anywhere cell phone coverage exists. Radio signals can be blocked by obstacles. The waves make it through trees and rugged landscapes, but not always as well as UHF frequencies do. UHF vs. VHF Two-Way Radios VHF Radio (Very High Frequency) The main difference between these two options is in the range of frequencies that they use. UHF vs VHF Radios. These transmissions, due to their higher frequency, penetrate through the Ionosphere, with little or no refraction. VHF radios offer a larger broadcast range, using radio waves from 30 MHz to 300 MHz. No. Satellite radios require a monthly service fee for the satellite usage. You can also try standing on top of something to make yourself taller. So mount your antenna as high-up on your vehicle as possible. If you live in an area with. Their biggest advantage is to extend the communication range beyond the capabilities of an RF system, but it's important to understand the differences, advantages, and disadvantages of each. These high frequencies are not able to travel beyond the horizon. The VHF wavelength is almost 10 times longer and more malleable than that of the UHF frequency. So more watts, along with a better antenna, equals longer range. Push-to-Talk Cellular uses the same cellular network that is used for cell phones. You often see ads for two-way radios saying "up to 36 miles" or more. This type of frequency can be used for both digital and analog broadcasts, and the VHF frequency band runs from 50 MHz to 225 MHz. If you’re considering purchasing a set of walkie talkies for commercial or personal use, then knowing the differences between these radio frequency bands will allow you to find the perfect set based on your individual needs, where the walkie talkies will be used, and how you plan on using them. The fundamental difference is in the range of frequencies that they use. General. But, VHF travels a lot further outdoor with lesser power than UHF. So, your radio's range is only limited by your computer network. is one of the most common questions people ask when buying a two-way radio. VHF microphones usually transmit at around 170Mhz to 216Mhz while UHF microphones transmit between 450Mhz and 952Mhz, which is over ten times the difference in the frequency range that devices can use. Feel free to search, filter or sort as you wish. VHF radios ideally need slightly larger aerials than UHF radios if they are to work well over long distances.
