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.

Regulatory Information

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.
