RTK Base Station Setup

Radio Power Setting to Meet Licensed ERP
The RTK Radio 450 system has been designed to meet a
wide range of possible congurations. This gives the end
user the ability to optimize the system for their specic
location and application. The end user must obtain a
site license from the local spectrum authorities. It is the
end user’s responsibility to ensure that RTK Radio 450
system parameters are congured correctly. Frequency,
bandwidth, output power and antenna height must all
conform to the granted license.
The frequency and output power of the RTK Radio
450 are programmable by the StarFire™ receiver. The
available ranges are:
NOTE: Cable loss measured on LMR400 Cable.
0.3 dB connector loss estimate included for cables.
0.1 dB connector loss estimate for direct
connection of the antenna.
Frequency 435 – 470 MHz
Frequency Resolution 6.25 kHz
Bandwidth 12.5 kHz
Radio Output Power
0.2 to 2.0 W
Amplier Output Power
5.0 to 50.0 W
When installing a base station, the total output power of
the system must be adjusted to comply with the granted
license. Cable losses, connection losses and the antenna
gain must be considered when calculating the total system
output power. The radio output power is congured using
GreenStar 3 System™ Display. Equivalent Radiated
Power (ERP) of the radio should be adjusted to ensure
that the total RTK Radio 450 system output power
complies with the license granted by the local spectrum
authority. The following tables can be used to determine
the appropriate setting.
NOTE: The use of an Amplier is only permitted
in the USA and Canada.
