The FCC But, VHF travels a lot further outdoor with lesser power than UHF. 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. So mount your antenna as high-up on your vehicle as possible. The trade-off for ultra-high frequency for distance is in building penetration or densely wooded areas. Walkie talkies that use this frequency will be a better choice for outdoor use. These radio waves will usually only go as far as line of sight. The higher your antenna, the farther the horizon. As an example, if you’re trying to communicate from one side of a building to the other, in between, there’s a thick metal wall with a small opening. satellites (and 9 spares in space) used for worldwide voice and data communication from hand-held satellite So to sum it up, it's a trade-off. monthly fee per radio. 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. The stronger the signal strength, the more it can withstand weakening when it passes through obstacles. The higher your antenna, the farther your signal can reach before hitting the horizon, therefore the longer your communication range. 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 … 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. To sum it up, the more watts a radio has, the stronger the signal. This means the distance to the horizon is the max communication range for walkie talkies, without the help of additional equipment that’s designed to boost the walkie talkie’s signal. If both waves were transmitted over a stretch of land that had no obstacles, VHF would still be able to travel twice as far. If you’re planning on using the walkie talkies inside, then you’ll want to go with UHF. Additionally, a walkie talkie runs off a small battery. radios from one office can talk to the other locations, even if these offices are thousands of miles apart. These transmissions, due to their higher frequency, penetrate through the Ionosphere, with little or no refraction. BUT, radio signals can travel through many non-metallic objects such as drywall, masonry, human bodies, furniture, and many other objects. Also, the denser an object, the more it reduces the signal strength. One of the best ways to increase range is to increase your height. So mount your antenna as high-up on your vehicle as possible. UHF vs VHF range. Let's discuss each of these. VHF waves are not very good at penetrating walls, buildings and Ever wonder why microwaves don't pass through the glass door? is connected to your network. Save my name, email, and website in this browser for the next time I comment. This means the signal follows the curvature of the earth. 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). Using a better-quality antenna is the easiest way to extend range. In between is a metal wall with a three-foot opening. Scroll to the bottom for notes. Remember, UHF signals are shorter than VHF, this is important when you're in or around buildings. VHF Vs.

No single factor is a silver-bullet to extend your communication range. One of the easiest ways to extend your range is by focusing on your antenna. The lowest high band often includes eight frequencies that are designated by the FCC. But the general rule-of-thumb is if you are using the radio primarily outdoors where you will have clear line-of-sight then VHF is a better choice because it's signal will travel farther. As an example, an antenna that’s six feet tall at both ends of transmission will have a max range of around five to six miles. "Why?" As UHF solidifies its position as the global standard and preferred RFID technology across vertical markets, tag prices continue to drop. VHF radios ideally need slightly larger aerials than UHF radios if they are to work well over long distances. Electromagnetic waves with the frequency range from 30MHz to 300MHz are called VHF. advantage, or disadvantage, of LTE is your radios work anywhere cell phone coverage exists. UHF vs VHF Radios. Lets deal with VHF vs UHF first; There are two main issues to consider. Commercial radio stations typically broadcast at 50,000 or 100,000 watts. No. Signal strength is another important factor when it comes to determining the distance a walkie talkie is able to communicate. Here’s what you need to know about how choosing to use either VHF and UHF affects your range: VHF. Please update your browser to fully experience this website. 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. 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. This maximum range is more theoretical than realistic. The smaller UHF signal will be able to easily pass through a door. However, this does not necessarily translate to more range. However, stubby antennas can reduce your range by up to 30% over a whip antenna. But since there isn't much you can do about mother nature, we will only give it a passing mention here. Keep in mind, just two or three feet can make a huge difference in terms of range. From the air it gets even better. So these low frequency signals can sometimes be received by radios below the horizon hundreds of miles away. 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. However, their signal can still only travel to the horizon. 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. radios, and some CB radios. This can even allow you to communicate across the Outdated browsers have security issues and don't follow new web standards. These bands are frequently used by maritime, military, emergency, and air traffic control systems. Most airband radios are 5 - 8 watts and typically have a range of around 200 miles. VHF, or very high frequency, operates at a lower level, covering the frequency range from 30 MHz to 300MHz. A radio wave is not able to pass through metal. VHF, or “very high frequency” radio bands are between 30-300MHz. Antennas on boats are much the same. The calculation of distances is based on the height of your antenna. A radio signal is weaker with a low battery. UHF vs VHF Radios. Purchasing a set of VHF or UHF walkie talkies can be a time-consuming process, considering all the confusing options available. A VHF radio is effective for communication of up to approximately 20 nautical miles, allowing for a greater range. The UHF signal (1 1/2 ft) passes through the door easily. UHF vs VHF Microphones. If you live in an area with hills, they are like metal, no radio signal will pass through them. ✔ 30-Day Return Policy VHF, or very high frequency, operates at a lower level, covering the frequency range from 30 MHz to … VHF radios offer a larger broadcast range, using radio waves from 30 MHz to 300 MHz. 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. Microwaves are extremely high frequency with small signal waves. Use a better antenna. The FCC has limited FRS channels to just a couple of watts. It’s pretty common to come across advertisements for two-way radios that claim a model has a range of thirty miles or more. So, your radio's range is only limited by your computer network. VHF features 130-174 megahertz, while UHF features 400-520-megahertz. VHF radios have been around for much longer and are quite cheaper compared to UHF. you ask. The trade-off you are making is longer distance (VHF), vs avoiding possible "dead spots" in and around structures (UHF). And the professional lot that have a much longer range and are professionally used. HF radio, for example, is vital for base stations communicating with each other over vast distances, thanks to ionospheric transmission. devices and other transceiver units. UHF vs VHF range. ✔ We Ship Anywhere in the USA Choose a whip antenna over a stubby antenna. The max wattage for every type of two-way radio is set by the FCC. VHF radio waves operate in a band between 30-300 megahertz, while UHF radio signals are propagated within 300 megahertz and 3 gigahertz. Handheld radios have 2 common types of antennas: stubby and whip. To sum it up, the higher your antenna the longer your communication range. However, these shorter signals are what allows these types of walkie talkies to excel at indoor use. Most two-way radios used today have a frequency range somewhere within 130MHz to 900MHz (except CB & Ham radios). 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. Other factors that can impact range include: Not all radio signals are the same. But if you do your research, you’ll find that many models don’t offer the type of range the manufacturers claim they do. Radios signals are sometimes blocked by solid objects.
