(Radio Frequency 476.425 – 477.400 MHZ)

UHF Radios are the most popular radio installed in 4 x 4 & trucks. They are best for communicating with a range of about 10 to 40km maximum. By using repeater stations it is possible to extend the range of these radios. So it is good to have one to communicate with fellow travellers in the area about road conditions, hazards, directions etc.
