UHF Radio Usage
*NOTICE*
Using a UHF radio requires a license. Operating a UHF radio without a license may result in
fines or other penalties. Be sure you comply with all local laws before operating a UHF radio.
Contact your local authorities ( such as, the FCC in the United States) for details.
Surveying in RTK mode has made UHF the most popular choice for communications between
Base and Rover receivers. Know the strengths and weaknesses of this technology to get the best
use out of your receiver. The quality and strength of the UHF signals translates into range for
UHF communications.
1. The system’s range will greatly depend on the local conditions. Topography, local
communications and even meteorological conditions play a major role in the possible range
of RTK communications. If needed, use a scanner to find clear channels.
2. The system’s range will increase by adjusting the Base station’s antenna using the following
methods.
• Ensure the Base radio has a fully charged battery.
• Use directional antennas and/or repeaters to increase your system’s range. Directional
antennas concentrate the signal power within a more narrow direction, significantly
increasing the range of your system.
• Check the TPS accessory line for items to raise the Base radio.
