UHF Radio Usage
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.
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.
