VHF radios are suited for long distances in and outdoor use. UHF radios operate at a higher frequency. … UHF radios are suited for indoor communication solutions, where obstacles are easily penetrable.
Which is better UHF or VHF?
In general, UHF radios are better for indoor use because their wavelengths are shorter and better able to penetrate through steel and concrete. … VHF radio signals tend to degrade more than UHF signals indoors.
Does VHF or UHF have longer range?
The main difference between UHF and VHF is range. UHF two-way radios have a range that is wider than VHF. This means that UHF frequencies have smaller waves that produce a greater range. They are more likely to pass barriers like rocks and trees easier.
Does military use UHF or VHF?
Quoting Buckfifty (Reply 13): Most of the time, travelling in international civilian airspace, the U.S. military will use VHF. It’s certainly changing towards less and less UHF only, and it’ll be the old fighters that will be last to go.
Can VHF talk to UHF?
VHF and UHF Walkie Talkies can’t talk to each other. The terms UHF and VHF refer to the “wavelength”. … That said, if a VHF wave and a UHF wave are transmitted over an area without obstructions, then the VHF wave would travel around twice as far. Since the VHF frequency waves are bigger, then the antenna must be bigger.
Are police radios UHF or VHF?
Police radios operate in a 700/800 MHz UHF band. This gives them a considerable amount of range which is pretty good in urban areas.

How far can a two way radio reach?
Wattage and Range of Coverage: Many two-way radios claim they have a range up to 25 miles in optimal conditions. Real-world conditions are usually not optimal, and in most situations, a radio’s actual range will be about 2 miles or less.
Does the military use VHF?
The primary military-only bands in the VHF high band are 138.00-144.00 and 148.00-150.775. … The Army uses 12.5 kHz spacing in their segments of the band. The primary communications mode is narrowband FM, but some AM is used by air units of the various services for tactical air-to-air comms.
What radio frequency do pilots use?
One of its roles is to allocate all radio bandwidths and frequencies. In the United States, VHF civil aircraft communications are placed in the 100 MHz band and allocated 760 channels within the range from 118.0-136.975 MHz. As a pilot, every frequency you talk on will fall within this range.
What band does military use?
The band 225-328.6 MHz is reserved for military uses by North Atlantic Treaty Organization (NATO), its member nations, and other U.S. allies. The band is harmonized among NATO-member nations for secure communications.
