Specifications

Use jumpers around metal backstay triangles on split backstay antennas.
Corrosion may cause up to several hundred ohms of resistance to occur even
though you may think that a metal-to-metal connection would be a good one.

The coupler is mounted using the proper mounting ears on the case. Choose a
location immediately adjacent to the antenna feed point. In trunk mounted
mobile installations, it is very important that the tuner is located so that the
antenna insulator is within a few centimeters of the antenna exit hole. Note
also that the antenna lead must pass through an insulated bushing. High volt-
age connecting cable must be used. (RG-8U cable with solid insulation may be
used if the outer shielding is removed). A protective housing is highly recom-
mended when the coupler is installed on the outside, or on the deck.

The antenna lead is connected to the high voltage insulator. During operation,
use two wrenches when tightening the nut to prevent the stud rotating. A
potential of several thousand volts may be present at the antenna terminal and
adequate protection must be made against accidental contact. It is also neces-
sary that the antenna is spaced at least 3 centimeters from the conducting sur-
face. Sharp points in the lead-in wire should be avoided to prevent corona dis-
charges.
