Radio repeater installation is not as simple as some people make out.

The some people I refer to are equipment hire companies.

A quick google search for two-way repeater hire will bring up hire companies.

For event hire you are likely to be offered a repeater and two clip on antennas.

There are two antennas, for receive and transmit.

You see the whole point of a repeater is to receive a weak signal, and retransmit it at a higher power level.

Repeaters therefore are devices used to increase signal range.

The Problem With a Two Antenna System

As I have already explained, a repeater can use two antennas, one for transmit and one for receive.

The problem that can arise is what is known as ‘ receiver desensitization’.

This is caused by some of the transmit signal being received by the receive antenna.
