How much difference does increased transmit power make? Very little on the range of the communications. Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). The VHF (very high frequency) range of the radio spectrum is the band extending from 30 MHz to 300 MHz. The wavelengths corresponding to these limit frequencies are 10 meters and 1 meter. In the VHF band, electromagnetic fields are affected by the earth's ionosphere and troposphere.

It is an excellent choice for various mission-critical long-range applications. SATEL XPRS VHF provides even more extensive coverage than the UHF variant of the
