HELPFUL HINTS
When mounting an Omni antennas on
a side arm of a tower, do not mount
the antenna close to the metal structure.
Place the antenna at least three to
four feet from the side of the tower,
more if possible. This minimizes the
distortion of the antenna pattern allowing
maximum gain.
To maximize the service life of the
installation, always apply waterproof
or antenna sealant tape to the RF connector
once the coaxial cable has been connected
to the base.
