An ultra high frequency (UHF) radio uses frequencies in the 300 MHz-3 GHz range for voice communications.Applications
The UHF radio permits voice communications between two or more radios. This walkie-talkie type radio is very common in maritime settings.Technologies
Communication takes place by the diffusion of electromagnetic waves generated by an electric current at a certain frequency. The receiver and speaker elements translate the waves into audible speech. Transmission is line-of-sight, with range limited by the horizon.How to choose
UHF communication is hampered by the fact that signal attenuation is possible at the highest frequencies. On the other hand, UHF penetration of partitions and walls offers advantages over lower frequencies.
- Good penetration of walls and partitions
- Affected by weather conditions
