UHF Data Radios

UHF data radio; modem

Ultra High Frequencies (UHF) have been used for voice and data radio communications since the middle of the last century. Bands withing the frequency range of 400-500MHz are used throughout the world for reliable communications.

In the USA, and in many other countries, the 450-512 MHz range is used for commercial wireless communications. Raveon has data radios in these bands:

A) 403-433MHz

B) 419-440MHz

C) 450-480MHz

D) 480-512MHz


UHF Radio Frequencies

The two major data radio modem bands used worldwide are the Very High Frequency (VHF) band and the Ultra High Frequency (UHF) band. Raveon provideds data radio modems in both bands.

There is no one best band. VHF and UHF each have advantages and disadvantages to them. UHF has a shorter wave length, so the antennas are more compact and less obtrusive. VHF antenna are typically larger than UHF, but in many instances, the communication range will be greater with a VHF system.

In open areas, most users will find that VHF data radios communicate further then UHF data radios. But in heavily wooded areas, or rough terrain, UHF data radios may work better. UHF signals penetrate foliage better, and will reflect off of rock and other obstructions quite well. UHF will also work indoors a little better than VHF and it penetrates buildings better.
