UHF OR VHF?
In South Africa a VHF radio (which stands for Very High Frequency) sends and receives between 136 MHz and 174 Mhz (megahertz). With an average wave length of 155 MHz, the sine wave is elongated and flat, which keeps the signal cohesive over large distances, making it ideal for offroaders who want to communicate over several kilometres. UHF radio (Ultra High Frequency) works between 430 MHz and 470 MHz in South Africa. This wave length has a more compact sine wave, which more easily penetrates obstacles like buildings, but at the cost of a reduced broadcast range. It therefore works better in a construction site than on the plains of the Marienfluss, unless you’re driving in convoy.
