BARRETT 950 HF TRANSCEIVER
PAGE 117
910 automatic tuning mobile antenna
A good earth (ground) to the main body of the vehicle is essential for efficient
operation of the antenna.
IMPORTANT INSTRUCTIONS
ensure
the whip spring base is tightened firmly onto the ABS antenna body
Note:
- Barrett P/N BC91000
The 910 Antenna plugs directly into the rear auxiliary connector of 550/530 or
950/930 transceivers using the cables supplied. Transceivers must have the
910/510 A
na option set during programming (refer to operation and
programming manual).
To achieve this clean all joints to bare metal and use
copper braid earth straps if any hinges or non-metallic joints are encountered.
When fitting the whip assembly to the Barrett 910 antenna, it is important to
. Barrett
communications recommends turning the spring base on to the ABS body lightly by
hand until it can be turned no further (ie; the mating faces of the spring base and
mounting stud on top of the ABS antenna body are touching). Then using a suitable
tool (ie; spanner) turn the lower
threaded part of the spring base a
further 20-30 degrees clockwise
while holding the top of the ABS
antenna body with a free hand.
Failure to fit the whip
assembly on the ABS antenna body
correctly in accordance with the
above instructions may lead to
eventual failure of the whip
mounting stud.
The antenna is supplied with a pre-
terminated 1.5 metre cable tail. This
should be routed into either the
engine compartment or boot (trunk)
of the vehicle.
A 6 metre pre-terminated extension
cable is supplied to connect the
antenna to the transceiver (this
cable may be extended to 12
metres by use of another extension
cable). If the joint between the
antenna stub cable and the
extension cable is in an exposed
position, a butyl rubber self
amalgamating tape should be used
to seal the joint. Do not wrap this
joint if it cannot be made completely
water tight as water will collect in the
joint and cause it to corrode.
