4.3 Antennas and Feed lines

Antennas

The transceiver may be used with a number of different antennas. The exact style and gain factor
depend on the physical size and layout of your system. Connection is made to the radio via a
TNC coaxial connector.
A directional Yagi (Figure 16) or corner reflector antenna is generally used at remote sites to
minimize interference to and from other users. Antennas of this type are available from several
manufacturers, including GE MDS. Contact your factory representative for details.

Feed lines
The selection of an antenna feed line is very important. Poor quality cable should be avoided as it
will result in power losses that may reduce the range and reliability of the radio system.
