5.2 Coupler Setup
Mount the coupler to the H-Beam, tower legs, or offshore
platform with the appropriate supplied hardware. See Equipment
Installation Manual.
Remove the access panel located above the tuning controls
panel.
Locate the antenna feedthrough insulator bushing, and care-
fully insert into the glass insulator panel according to the
instruction sheet packaged with the insulator. Do not over
tighten or stress the insulator components. Locate the
rainshield and install acording to the enclosed directions.
Connect the wire from the top of the coil assembly in the
coupler to the insulator bushing. Attach the antenna lead
to the external end of the insulator bushing. Dress all leads
at least 2 inches from metal surfaces.
Locate and install the lightning arrestor with the two screws
located between the insulator bushing and the front access
door. Adjust the spark gap if necessary to approximately I"
(2.5 cm).
Connect the cables according to the, "Antenna Coupler Cable
Connections," and "Transmitter Diagram." (See table of
figures.)
Attach the ground wire from the counterpoise system or offshore
platform frame to the copper ground lug on the coupler.
Set all taps according to the following table and charts in
this section. Fine tuning taps are chosen with a front panel
switch. The coarse tap is chosen by connecting a clip lead
to the proper coil tap behind the coil access panel. A
permanent connection will be made later. Set the Setup/ Run
switch on the Autotune PWB to Run.
