Antenna Installation
Precautions
WARNING
Don't expose personnel to the medical hazards of intense radio fre-
quency (RF) radiation. Whenever working on the tower in the area of
the antenna, turn off all transmitters and lock them out so that they can-
not be turned on accidentally.
WARNING
Material safety data sheets for the chemicals you may encounter are
appended at the end of this manual. Study them carefully before begin-
ning installation.
CAUTION
O-rings are made of silicone. Do not lubricate them with silicone grease,
as this will soften the O-ring. Use only a light lubricating coat of O-Lube
(provided) or petroleum jelly; too much may hamper electrical contact
and contaminate the interior of the system.
CAUTION
Feedstrap orientation is critical to performance. In general, the feed-
straps in a full-wave-spaced antenna will all be oriented the same, while
those in a half-wave-spaced antenna will alternate.
Install each radiator
in accordance with its stenciled bay numbers and its "up-arrow" sticker.
Study your antenna
CAUTION
These procedures are guidelines. Assemble components exactly in
accordance with the installation drawing. If you don’t, the antenna may
not perform as expected.
It will be easiest to mount the radiators, feedline mounts, and radomes (if
applicable) onto the feedline sections before the feedline sections are
mounted on the tower.
Determine what, if any, icing protection your antenna has.
If your antenna element looks like
