Antenna Installation
(4) Using a hardware mounting kit (four bolts with nuts and washers),
secure the back support mount to the upper feedline mount flange and
lower feedline mount flange.
NOTE
Use shims or washers as necessary to fit the back support mount to the
mount flanges.
NOTE
You may need to save final tightening of this hardware until the feedline
is installed on the tower.
c. Repeat the above steps for the remaining feedline sections.
Install the bay
radiators
a. Attach the bay radiator to the feedline (
Figure 2
):
(1) Roll the feedline section over so that the baymount flange points
upward. Secure the feedline section at the brass end, using clamps, to
prevent its turning with the weight of the radiator.
CAUTION
All contact surfaces and openings to the interior of the components are
protected from contamination and from physical damage by protective
covers and plastic bags. Do not remove this protection until ready to
connect the components.
(2) Remove the plastic bag and protective cover from the baymount flange.
(3) Make sure an inner conductor connector is in place in the inner
conductor of the baymount flange of the feedline.
NOTE
Feedline flange hardware and O-ring are shipped separately in a plastic
bag. Each bag contains the hardware and O-ring for one flange.
CAUTION
Be sure the baymount flange O-ring is properly seated in its groove and
not pinched between the flange contact surfaces.
(4) Coat the baymount flange O-ring lightly with O-Lube (supplied with the
antenna), then install it in the O-ring groove in the baymount flange.
(5) Remove the matching radiator assembly from its protective plastic bag.
CAUTION
Be sure the radiator’s inner conductor fits cleanly over the baymount’s
inner conductor connector. If any of the fingers of the connector are
forced outside the radiator’s inner conductor (we call this a "split bul-
let"), this will cause arcing and damage to the antenna.
(6) Align the radiator with the baymount flange as shown, with the top of
the radiator pointing toward the top of the feedline. Carefully place the
radiator into position over the flange studs and inner conductor
connector.
(7) First snug the baymount flange hardware, then tighten in the sequence
shown in
Figure 3
. Torque in accordance with
Table 1
on page 7.
Important
Be very careful not to dis-
turb or damage the feed
strap when handling the
bay radiator.
