4 INSTALLATION
4.1 Car installation
The front module can be disconnected from the radio module, and mounted separately
in a position close to the operator.
The two modules are connected with a special CAT6 cable, to be ordered separately.
- Screw up the radio module using the bracket. - Screw up the front module and connect the front module to the radio module. - Connect the power leads directly to the car battery, using fuses on both leads. The
RED lead is the positive (+).
- Connect the antenna to the BNC connector at the back plate of the TR-810. - Connect the microphone to the front module.

4.2.1 External antenna
The antenna should be of good quality with regards to gain and VSWR to obtain maximum
performance. Make sure that the VSWR on the antenna is low, and that the cable from the
transceiver to the antenna is of good quality to avoid mismatch problems.
In areas were thunderstorms and lightning is a problem, surge arrestors should be mounted
between the antenna connector and the antenna cable. The arrestors must be of good quality
and be capable of handling the output power of the transmitter.
The antenna input of the transceiver is the BNC-type antenna connector on the back of the
transceiver.
