21. Thread nylon reed into an-
tenna drive. Make sure that bot-
tom insulator and water seal
washer are in place and that the
small diameter end of the bottom
insulator is downward. Apply 12
volts D.C. to blue power lead to
assist feeding operation. Keep
nylon reed straight to avoid
kinking.
NOTE: Position water seal wash-
er and bottom insulator in the
22. Push 0.40 inch diameter sec-
tion of mast and insulator bushing
into tubular fitting (see Figure
11-13). Make sure that the upper
edge of insulator bushing flange
is below the 3 holes in the tubular
fitting of antenna drive.
23. Install support tube.
24. Slip body and upper insulator
assembly over the 0.40 inch sec-
tion of mast, but do not connect
to support tube. Make sure that
the free-end of the hook-up wire
extends below the lower edge of
the body and upper insulator
assembly.

before the nylon reed completely
disappears in drive assembly.

hook-up wire to the 0.40 inch
diameter section of the mast sec-
tion, using rosin flux solder (see
Figure 11-12).
26. Position and reassemble body
and upper insulator to support
tube.
27. Perform antenna adjustment
procedure (ref. subpar. "f").
28. Reassemble 3/8" hex nut and
drive cover onto antenna drive
and make sure that the vent hole
in the drive cover is at the top
when the antenna is installed in
the car.
29. Reseal the antenna drive with
body sealer and make sure that
neither the vent hole in the drive
cover, nor the drain hole in the
antenna drive is plugged.
f. Adjustment of Antenna
1. Remove the drive cover and
3/8 inch hex nut from the antenna
drive.
2. Place antenna drive in a vise
so that the center line of antenna
drive is parallel to the bench top.
3. Using 12 volts D.C—adjust
mast tip approximately 6 inches
from the extreme down position.
4. Connect one end of a wire se-
curely to the mast just below the
tip and the other end to a 25 lb.
