NOTE
To prevent moisture from entering the radio, do not mount the case with the cable connectors
pointing up. Also, dress all cables to prevent moisture from running along the cables and into the
radio.
The figure above shows the mounting brackets at the furthest in (shortest distance) apart. The standard
mounting brackets can be mounted with the second pair of holes to increase the distance. The new width
of the radio with the mounting brackets would be 8.5 inches (216 mm).
Optional DIN Rail Mounting
3.2.1
The unit may be mounted with an optional 35 mm DIN Rail Mounting Bracket Kit (Part No. 03-4125A04).
Equipment cabinets and racks of modern design often employ this type of mounting. Once the DIN
bracket is attached to the radio, it allows for quick installation and removal of the radio from its mounting
rail without the need for tools.
The DIN Rail bracket attaches to the unit's case along the left side of the transceiver (DB25 connector
side) with two screws. Ensure that the pull tab is located towards the back of the radio. The entire
assembly then attaches to the mounting rail with the connectors facing upwards.

Antennas and Feedlines
Antennas
3.3.1
The transceiver may be used with several 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 N coaxial connector.
Contact your factory representative for details for Antennas available from GE MDS for this radio.
Feedlines
3.3.2
The selection of an antenna feedline 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.
