VHF frequencies can penetrate objects better than UHF. So how far can you really expect to talk? Models that run on a higher wattage mean a walkie talkie’s batteries will not last very long. As I mentioned above, UHF and VHF are the two most commonly used radio signals. 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. This 44 inch long UHF antenna with 18 x UHF elements helps you get the best UHF range possible (which is where most if not all channels real frequencies are today). Although microwaves are small, they are still bigger than the tiny holes in the metal mesh. Option 1 vs Option 2: For those that still have VHF stations in their area, choose Option 2 for both long range UHF & VHF. 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? VHF waves are not very good at penetrating walls, buildings and When we said "the distance to the horizon is the maximum communication range" we didn't mention one key factor, your antenna. Push-to-Talk Cellular uses the same cellular network that is used for cell phones. Remember the higher your antenna the father the horizon is. Television broadcast and FM radio broadcast (usually utilizes the 88MHz – 108MHz range) are two major uses of VHF. However, these antennas can reduce the range up to thirty percent compared to a whip antenna. As a general rule, the lower the frequency, the greater distance it can travel. A higher frequency in MHz means just what it sounds like, that the waves are more frequent. One important characteristic of radio waves is the wavelength which is the distance between peaks on a wave: Wavelength is inversely proportional to the frequency. A radio wave is not able to pass through metal. Metal will not be your friend when you’re using a walkie talkie since radio waves are not able to pass through it. Walkie talkies that use this frequency will be a better choice for outdoor use. implement. VHF vs UHF – Real World Applications LTE uses a private cellular network. If you’re using a GMRS/FRS model, try the GMRS channels. Not every antenna on a walkie talkie is the same. This can even allow you to communicate across the 4. 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). Each mode of radio wave propagation is useful in different settings. In other words, the exact distance to the horizon varies depending on your antenna height. So just having more watts without a better antenna is like having a large funnel with a small hole. VHF propagation is ‘line of sight’ in nature and so is restricted to shorter-range communications. If you’re not sure which type of system will work for you, then always go with UHF. Handheld radios have 2 common types of antennas: stubby and whip. But if you do your research, you’ll find that many models don’t offer the type of range the manufacturers claim they do. So, what can they do to improve their range? Mobile radios usually broadcast from 25 to 100 watts maximum. UHF (ultra high frequency) signals operate at the higher end of the radio frequency spectrum. 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. They differ in how they travel, and how they react when they encounter materials. The above graph shows the distance range between two mobile vehicles with basic vehicle whip antennas. ✔ Excellent Service (BBB A+ Rating) 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). 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. areas where infrastructure does not exist. you say. Their signal is much stronger than a handheld radio, therefore less affected by obstacles. The fundamental difference is in the range of frequencies that they use. An unlicensed radio, such as an FRS model is usually limited to two watts, while CB radios come in at four watts. 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). At that frequency, the effects of the capacitor and inductor cancel. connection. Heavy Duty Insane Gain XPS-1500 TV Antenna Tip: What is nice about of long range Insane Gain XPS-1500 model, is if your area still has challenging VHF stations, the VHF performance is actually upgradeable, if it's needed. The UHF signal (1 1/2 ft) passes through the door easily. The two most commonly used frequency ranges for two-way radios are VHF (Very High Frequency 130-174MHz), and UHF (Ultra High Frequency 400-520MHz). 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. However, their signal can still only travel to the horizon. A higher frequency in MHz means just what it sounds like, that the waves are more frequent. radios from one office can talk to the other locations, even if these offices are thousands of miles apart. VHF radio waves operate in a band between 30-300 megahertz, while UHF radio signals are propagated within 300 megahertz and 3 gigahertz. 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. VHF signals are often blocked by metal within the building. Very High Frequency (VHF) communications offer plenty of positives advantages: such as sound … However, radio signals are able to travel through many types of non-metallic objects including furniture, human bodies, masonry, and drywall. Radio waves generally won't pass through metal or hills at all. 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. Like the VHF region, the UHF region contains several bands that are used for wireless microphone systems. This makes VHF easier to broadcast over a long range. Other Examples: For handheld radios, instead of a stubby antenna, get a whip antenna. UHF and VHF frequencies are part of the overall electromagnetic spectrum. Assumes standard equipment. UHF allows for a faster data transfer rate, up to 20 times the range and speed of HF systems. This is because theVHF signal waves can travel a … Their peaks and troughs propagate more closely together. advantage, or disadvantage, of LTE is your radios work anywhere cell phone coverage exists. However, certain physical, regulatory, and economic differences between VHF and UHF regions should be noted here. UHF, or ultra high frequency, relates to the band that covers the range between 300 megahertz or MHz and 3000MHz. When looking at your TV and the channels, the UHF channels will usually be numbered higher. 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. A radio signal is weaker with a low battery. 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. Most commercial UHF and VHF radios have two to three power modes. They unfortunately have less channels though, which can lead to congestion and interference from other nearby two-way radios. Low band ranges of around forty-nine megahertz will include transmissions of radio-controlled toys, cordless phones, wireless microphones, and more. 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…. However, while VHF can easily pass through obstacles farther and easily, it doesn’t always make this type of signal the best choice. Other handheld radios such as marine, aviation, and licensed land-based radios such as: LMR, Ham, & GRMS are limited to 5 watts, again radios with SSB can have 12 watts. Not so fast. \"How far can this radio talk?\" is one of the most common questions people ask when buying a two-way radio. If you live in an area with. Posted by 1 year ago. Network radios (also called Radio-Over-IP, RoIP, IP or WALN) radios communicate through the internet via a wireless internet Perfect for those looking for the longest range possible and easy setup, such as companies operating vehicle fleets in large metropolitan areas. Unfortunately, there are lots of variables involved, and so there is no easy and specific answer. These higher frequencies can travel in straight lines that are called line of sight signals, unlike frequencies that are below two megahertz. The waves make it through trees and rugged landscapes, but not as well as UHF frequencies do. Use a better antenna. The two frequency ranges (also called "frequency bands") used in most two-way radios are VHF (Very High Frequency), and UHF (Ultra High Frequency). Radio waves can not pass through metal. No. Compare that to a handheld two-way radio which uses between 1/2 - 5 watts. Commercial radio stations typically broadcast at 50,000 or 100,000 watts. So mount your antenna as high-up on your vehicle as possible. However, the disadvantage of UHF is that its range will be less outside when compared to VHF. If you live in an area with hills, they are like metal, no radio signal will pass through them. That's because the type of equipment and terrain can greatly affect your range. is connected to your network. devices and other transceiver units. Make sure that your walkie talkie is placed on the highest power mode. UHF vs. VHF: Frequencies and Wavelengths. Philadelphia UHF two-way radios operate from 403 to 430 MHz, 450 to 470MHz, and 450 to 527 MHz. So if range is important to you, look for a radio with a whip antenna, or at the very least, one where you can remove the stubby antenna and replace it with a whip antenna. Purchasing a set of VHF or UHF walkie talkies can be a time-consuming process, considering all the confusing options available. *Single side band (SSB) is used in some amateur (ham) ✔ Secure Online Purchasing Consider some of the new technologies listed in the next section. The two most commonly used frequency ranges for two-way radios are VHF (Very High Frequency 130-174MHz), and UHF (Ultra High Frequency 400-520MHz). They can more easily penetrate metal and concrete structures, which makes UHF radios a good choice in built-up areas like towns and cities, or for densely wooded or hilly areas. This range can be significantly boosted by a two-way repeater. Installed in vehicles, they run off the vehicle's battery. If you live in an area with hills, just like metal, a radio signal will be unable to pass through it. So these low frequency signals can sometimes be received by radios below the horizon hundreds of miles away. The transmission is high enough that it can penetrate through walls, which is what makes it a better choice for indoor use. 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. 1.2 These bands are used by a wide range of parties, including Ministry of Defence (MOD), Emergency Services (ES) and civil users referred to as Business Radio (BR). If you are at the edge of your communication range and your signal is weak, One of the easiest ways to increase your range is to increase your height. When we said "the distance to the horizon is the maximum communication range" we didn't mention one key factor, your antenna. Low VHF signals (channels 2-6) and High VHF signals (channels 7-12) can bounce further than this, but most digital TV channels are on the UHF band (channels 13-26) - which is line-of-sight transmission. These low frequency signals can be received by walkie talkies that are below the horizon, hundreds of miles away. Choose a whip antenna over a stubby antenna. Other types of handheld radios such as HAM and GRMS are limited to five watts. The trade-off for ultra-high frequency for distance is in building penetration or densely wooded areas. Their signal is much stronger than a handheld radio, therefore less affected by obstacles. The trade-off for ultra-high frequency for distance is in building penetration or densely wooded areas. If you really need to know about the effects of weather on radio transmission then that's a whole other conversation. UHF is the better all around signal and is by far the most popular, so if you are in doubt, choose UHF. Neither is inherently better, they each have strong points and weaknesses. One last thing we didn't mention is the weather, and other atmospheric conditions can affect radio transmissions. Beachwood Merchandising Corporation © 2012-2020 All Rights Reserved. For example, 54 to 72 MHz and 76 to 88 MHz are used in the United States for VHF channels 2 through 6, which is known as Band I internationally. What can you do to make it more like 6 miles than 4 miles? 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. The smaller UHF signal will be able to easily pass through a door. However, low frequencies are very vulnerable to other issues. 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. 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. country. Both UHF and VHF radios are prone to line of sight factors, but VHF a little more so. VHF walkies operate on the frequencies between 136 and 174 MHz, they work over large distances with lower power consumption. Archived. Be sure your.

Other circuitry is used to detect and remove noise fr… Perfect for those needing global or back-country remote communications, The waves make it through trees and rugged landscapes, but not always as well as UHF frequencies do. UHF vs VHF Microphones. Basically, when it comes to VHF vs UHF range, it’s often a trade-off. obstructions the range is approximately 4+ miles. VHF radios offer a larger broadcast range, using radio waves from 30 MHz to 300 MHz. Download the UHF vs. HF PDF. Another consideration is hills. Also, mount your antenna in a straight-up position, not at an angle. Installed in vehicles, they run off the vehicle's battery. If you’re looking for a … 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 … receiving radios must have SSB So how far can you really expect to talk? If you’re planning on using the walkie talkies inside, then you’ll want to go with UHF. Even comparing handheld UHF vs VHF two-way radios, the maximum range of both is typically about 4 miles. 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. Most models will use two common types: Many radios on the market these days have stubby antennas since they make it easier to place the walkie talkie in a pocket or backpack. It’s also able to travel farther. The Iridium satellite constellation is a system of 66 active UHF is approximately 1 ½ feet wide, while VHF wavelengths are around five. The ac current and … 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. 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). 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. Both types have their pros and cons, so neither one is inherently better than the other. To sum it up, the more watts a radio has, the stronger the signal. This frequency is often used for FM radio broadcasts, marine communications, long range data communications, and two-way land mobile radio systems. UHF = "Ultra High Frequency." Remember the higher your antenna the father the horizon is. UHF is the better all around signal and is by far the most popular, so if you are in doubt, choose UHF. There’s a formula used for calculating the distance to the horizon based on the antenna’s height, however, it’s pretty technical. VHF band is sandwiched between HF (High Frequency) and UHF (Ultra High Frequency) bands in spectrum. A stronger signal is capable of withstanding successive passes through obstacles, allowing it to travel farther. 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. They also have a reputation for hugging the earth better, which provides an improved performance in hilly terrain. First, not all radio signals are the same. Default sorting is by 3rd order Dynamic Range (wide spaced). Ever wonder why microwaves don't pass through the glass door? This type of frequency is less likely to be interrupted by electrical equipment, atmospheric noise, and other types of interference. A VHF radio is effective for communication of up to approximately 20 nautical miles, allowing for a greater range. An important variable when considering the distance is whether the signal frequency is VHF vs. UHF. The waves make it through trees and rugged landscapes, but not as well as UHF frequencies do. However, when communicating on SSB channels, both the sending and However, in the outdoors, it tends to have better range than UHF in open environments, such as farming, hiking and outdoor activities. Thus, two people carrying a handheld two-way radio, the maximum communication distance on flat ground with no obstructions is approximately 6 miles. While the UHF signal isn’t able to travel as far as VHF, they will do a much better job of penetrating concrete, steel, and wood, and will give you better performance and range around buildings and in urban environments. In some other countries, the high-band VHF range extends to 230 MHz. You can get radios that use either UHF (Ultra High Frequency) or VHF (Very High Frequency). However, in remote areas with no cell coverage these radios will not work. Save my name, email, and website in this browser for the next time I comment. These are averages. You can also try standing on top of something to make yourself taller. Remember, UHF signals are shorter than VHF, this is important when you're in or around buildings. 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. A higher range of fifty-four megahertz will operate TV channels and certain types of wireless systems.     5ft 7in person standing on the ground (average eye-level height), the horizon is 4.7 kilometres away (2.9 miles)    6ft 7in person standing on the ground, the horizon is 5 kilometres away (3.1 miles)    Person standing on a 100 metre (330 ft) hill, the horizon is 36 kilometres away (22 miles)    Person standing at the top of a 828 metre mountain (2,717 ft), the horizon is 103 kilometres away (64 miles), ✔ Authorized Dealer HF radio, for example, is vital for base stations communicating with each other over vast distances, thanks to ionospheric transmission. Mobile radios usually broadcast from 25 to 100 watts maximum. 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. Use a better antenna! 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. UHF vs VHF Radios. Either VHF or UHF radio technology can work for you if you don’t really have a long range to cover. I was told: UHF is best for urban areas or inside the building as it penetrates well thru the wall than VHF does. This makes VHF easier to broadcast over a long range. VHF (Very high frequency) is the ITU term for the range of radiofrequency electromagnetic waves (radio waves) that are from 30 to 300 megahertz (MHz). First, not all radio signals are the same. See what a difference antenna height can make? You may only get 4 miles or even less. The above graph shows the distance range between two mobile vehicles with basic vehicle whip antennas. This means the signal follows the curvature of the earth. Close. Another important factor in determining the distance a radio can communicate is it's signal strength. So to sum it up, it's a trade-off. Radios signals are sometimes blocked by solid objects. Scroll to the bottom for notes. Even though VHF can pass through obstacles better and travel farther, that doesn’t mean it's always the better choice. VHF, or very high frequency, operates at a lower level, covering the frequency range from 30 MHz to 300MHz. channels. But keep reading, there are other things to consider as well, such as power and obstructions. "Sign me up for VHF!" Aviation radios in the air have the most advantage, no obstacles and you're already very high! A sampling of domestic platforms include the F-16, F/A-18, A-10, F-117, F-15, MV-22, CV-22, AH-1W, AWACS, B … Expect Note: Range and coverage are estimates and are not guaranteed." Yaesu FT-8900R Quad Band Hi Power FM Amateur Ham Radio Transceiver. 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, low frequencies are susceptible to some other issues. And the professional lot that have a much longer range and are professionally used. Basically, the higher the antenna, the longer the communication range will be. Always make sure your battery is fully charged. Feel free to search, filter or sort as you wish. Using a better-quality antenna is the easiest way to extend range. Satellite radios communicate through an array of satellites know as the Iridium satellite constellation. However, there are additional factors to consider. Antennas on boats are much the same. Antennas on cars are usually mounted on the roof or trunk and can extend several feet above the car.
