What types of radios do police use?
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. The P25 radio systems give an improved range for officers. Getting a larger antenna on your walkie talkie can improve the amount of range you receive.
Can police radios be tracked?
Absolutely! It’s an old technique called direction-finding. Ham radio operators sometimes do it for fun in what’s called a “fox hunt” where they need to locate a hidden transmitter. Using directional antennas and signal strength equipment you can triangulate a signal with a simple handheld radio.

Is VHF or UHF better?
VHF radios are suited for long distances in and outdoor use. UHF radios operate at a higher frequency. This makes them ideal for wireless communications that need to penetrate through buildings, walls, or concrete. UHF radios are suited for indoor communication solutions, where obstacles are easily penetrable.
