Figure 9. Feedline flange detail
CAUTION
The feedline inner conductors include "bullet guides" (see
Figure 9
) to
help prevent split bullets. Be sure the bullet guides are in place before
assembly.
CAUTION
Do not overtighten the feedline flange hardware (see
Table 1
on
page 7). Only the contact surfaces should touch, as shown in
Figure 9
.
(2) As each feedline section is lifted into place, remove the plastic bags and
protective covers from the flanges and install an O-ring, lubricating it
with a light coat of petroleum jelly (provided with the antenna).
NOTE
In most cases, the mounts are reversible to clear tower cross-members
and other obstructions.
(3) Align the mounts to the tower leg(s) or mounting pole, then secure
them to the back support mount using box bolts.
(4) Last, secure the mounts to the tower in accordance with your
installation drawing (commonly using U-bolts).
(5) When all mounts are in place, sight along them vertically and align them
before finally tightening the hardware.
c. Touch up any exposed metal on the tower or pole.
