Using the UHF Kit Option
The SP80 UHF kit is an option that you can use to implement 
a radio-based, standalone RTK base/rover system (see 
Optional Accessories on page 3 for more details on all the 
items provided in this kit).
With this configuration, you have full control of your base as 
you can choose where and when to install and operate it.
You will need two SP80 UHF kits to implement a complete 
radio-based RTK base/rover system. One kit will be installed 
on base side, the other on rover side.
You will also need two UHF whip antennas, one at the base, 
one at the rover. UHF antennas may be ordered separately, or 
as part of specific accessories kits that you may need if you 
wish to install the UHF antenna used at the base on a 
separate pole. See Other Optional Accessories on page 4 for 
further details.
Configuring your radio modules is required before you can use 
them. This procedure is discussed in Configuring the UHF 
Module on page 48.
Internal vs. External Power Source for a Base Using a UHF 
Radio Transmitter: This point has already been discussed 
when introducing the possible base setups. Please refer to 
Internal vs. External Power Source on page 30.
When a radio is used at the base, there is more power needed 
than in any other base setup. In this case, the use of an 
external power source (a 12 V battery) is recommended, 
especially if the base is operated unattended for a full day’s 
work.
