ART. 432 GSM ANTENNA
The Art.432 GSM antenna connects to the SMA female bulkhead connection on
the rear of the Art.150 GSM module. A GSM antenna with an SMA male connector
should be used (refer to
Fig.7
).
Antenna Parts
1. GSM antenna with magnetic base.
2. Self-threading screw
(Ø3.5mm x 9.5mm)
.
3. Aluminium L bracket for mounting.
4. SMA male connector
(cable length 2.5m)
.
5. Expansion type wall plugs
(Ø6mm)
.
6. Self-threading screw
(Ø4mm x 30mm)

IMPORTANT NOTE: An antenna must always be fitted for the GSM module to
work. Always route the GSM antenna cable away from the microphone wires
and the power supply wires to avoid interference on the speech channels.
In instances where there is a tight fitting space for the SMA male connector on
the antenna cable the right angled SMA adapter can be used to help reroute the
cable down the back side of the GSM module.
