Technical information

objects will reduce the danger of damaging the QMS. For
instance, if driving in rough terrain, the QMS is likely to
be hit by trees, stumps, or rocks. If the unit were
mounted on the back of the vehicle, damage would be
less likely to occur than if a side mount was used.
3. If you will be traveling in an area where overhead
restrictions may prevent use of your SG-303 antenna,
the antenna should be folded down and secured to pre-
vent damage from brush, trees, or low structures.
4. When connecting the coupler to the radio/trans-
ceiver, a passageway for the control cable (consisting of
an RG-58 coax cable, control wire, power, and ground,
plus the optional tuned indicator wire) will need to be
provided.
5. Once a location for the QMS has been selected,
mounting becomes a simple task. The QMS enclosure
mounts in virtually any attitude and the straps can be
moved to either side of the enclosure to accommodate
the vehicle .
Installation Precautions. To ensure safe operation of your
QMS system, the following installation, mechanical, and elec-
trical precautions should always be taken:
1. Insure that all four straps are pulled down tightly
and the suction cup feet have been securely com-
pressed.
2. Insure that the high voltage wire protruding from
your antenna system is not routed near any metallic
objects such as your vehicle’s frame or metal posts. This
wire is part of the flexible insulator of your QMS sys-
tem.
3. Insure that the ground braid is attached to a good
