Neither is inherently better, they each have strong points and weaknesses. If you live in an area with. Are you guaranteed to get 6 miles? Another consideration is hills. This maximum range is more theoretical than realistic. 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. These repeaters typically have about 50 watts of power, extending the reach to about 50 miles of coverage. Another important factor in determining the distance a radio can communicate is it's signal strength. They differ in how they travel, and how they react when they encounter materials. These frequencies are referred to as travel frequencies since they can be used all over the country, without the fear of interference. If you’re experiencing a weak signal and you’re at the end of your range, try moving to a higher location, such as climbing up a hill. The two most regularly used frequency ranges for two-way radios are VHF (Very High-Frequency 130-174MHz), and UHF (Ultra High-Frequency 400-520MHz). Perfect for those needing global or back-country remote communications, 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 … That's because the type of equipment and terrain can greatly affect your range. In general, VHF radios operate in the 138-174 MHz frequency band and UHF radios operate in the 400-512 MHz frequency band making UHF roughly three times higher in frequency than VHF. If you must have a longer range than most radios can provide, then consider either buying a repeater, contacting a repeater service, or look to satellite, network, or LTE radios. Consider some of the new technologies listed in the next section. Keep in mind, UHF signals are shorter, which will be important around or in buildings. UHF allows for a faster data transfer rate, up to 20 times the range and speed of HF systems. 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). This makes VHF easier to broadcast over a long range. How often are you on top of a mountain? In some cases, using VHF will be a better choice, while in others, UHF will be the smarter decision.

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. 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. So just having more watts without a better antenna is like having a large funnel with a small hole. Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.
