Mounting the Barrett 2019 Automatic Tuning Mobile HF Antenna
The Barrett 2019 antenna should be mounted in positions similar to those
illustrated in the diagrams on the following pages. Select a position free from
excessive vibration. A bracket, fabricated to withstand the forces and vibration that
can be expected during off-road driving, should be used to mount the antenna to
the vehicle. When locating the mounting position for the antenna ensure that the
antenna body, when flexing on its vibration mount, cannot come into contact with
other parts of the vehicle. The antenna should be mounted as far from surrounding
objects on the vehicle as possible.
The antenna is supplied with one middle section and one top whip section (Barrett
P/N: BCA201901), a tapered black spring (Barrett P/N: BCA201903), an antenna
installation guide and a pre-terminated 6 metre control cable to suit the Barrett
2019 antenna to transceiver. A 6 metre (Barrett P/N: BCA201904) or 10 metre
(Barrett P/N: BCA201902) extension cable for the control cable is also available.
The control cable should be routed into either the engine compartment or boot
(trunk) of the vehicle. If the joint between the antenna control 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.
A good earth (ground) to the main body of the vehicle is essential for
efficient operation of the antenna. To achieve this clean all joints to bare metal
and use copper braid earth straps if any non-metallic joints are encountered.
After mounting the main body of the antenna, screw the black base spring onto the
antenna body followed by the whip section.
Important Information
It is ESSENTIAL to maintain the minimum clearances between the antenna
and surrounding metal work as indicated in the diagrams. FAILURE TO
MAINTAIN THESE CLEARANCES WILL NOT ONLY REDUCE THE
EFFICIENCY OF THE BARRETT 2019 AUTOMATIC TUNING MOBILE HF
ANTENNA BUT MAY ALSO LEAD TO INTERNAL RF ARCING AND FAILURE.
