Base Mounting the antenna
The thread used on the base of antenna (1 inch, 14 TPI)
is an industry standard used on a wide range of commer-
cially available mounting brackets or extension poles.
Due to the manufacturing process of the mounting brack-
ets, the antenna may not tighten all the way down onto all
the threads. This is of no concern however as the anten-
na must be tightened until the antenna stops rotating.
1. When passing the antenna cable through a mounting
bracket or extension pole, make sure to pass the ca-
ble through the antenna base.
NOTES:
When routing the antenna cable along the outside of
the extension pole, pass the cable through the groove
as shown by the dotted lines in the gure on the right.
(Please cut the blank panel with a long-nose pliers.)
The antenna cable can be cut and spliced to ease installation. Care must be taken when reconnecting
the antenna cable to protect from water and corrosion.
2. Mount the antenna base to the antenna using the supplied three screws.
3. Screw the antenna base to the mounting bracket or extension pole.
4. Install the mounting bracket or extension pole.

recommended to verify correct opera-
tion in the desired location.
