Do you need an antenna for UHF radio?

There is nothing between CB and UHF radios . CB is UHF there is 3 bands for radios VHF,UHF,AM. The only difference is that the railways use set channels that they hold the transmit rights for the same as the Police, CFA, SES & Ambo’s. Its the same thing.

All UHF radios transmit best on a line of sight basis, which means that it’s important to position an antenna in such a way as to provide maximum coverage .

UHF is the better all around signal and is by far the most popular, so if you are in doubt, choose UHF. UHF signals don’t travel quite as far outdoors as VHF signals, but they do a better job of penetrating wood, steel, and concrete, giving you better range and performance in urban environments and around buildings.

There are a range of additional uses for a UHF radio. When you’re travelling in a convoy, chatting over the UHF is the easiest way to stay in communication with each other . Just avoid the popular stations (such as channel 40), as you don’t want to clog up the airwaves with regular chit-chat.

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.

UHF radio signals are used in many facets of life including satellite communication, GPS, Wi-Fi, Bluetooth, walkie-talkies, cordless phones, cell phones, and television broadcasting . A large advantage of UHF transmission is the short wavelengths produced by the high frequency.21 Eyl 2015
