Installation
Installing the Rotor system for portable use is not difficult.
Before starting the installation VERIFY that the site is in a
safe location to erect an antenna system of the size you
are using.
Make sure there are NO overhead power
wires nearby
. Also make sure there are NO buildings,
structures, or trees that the turning antenna could strike
causing potential damage.
Eye protection should be worn when installing the antennas. Large
antennas with crossing elements can be an eye danger especially
when installing them at eye level.
Even though this is a low power 12 Volt DC device, the high gear ratio
of the mechanism could cause damage if rotating your antenna into
fixed objects.
Use the provided hook-and-loop fastener to attach the feed line Coax
and Rotor Cable to your tripod or mast in a few locations to keep the
cables from dragging on the ground or moving in the wind. It is
recommended to attach the cables to the mast in the opposite
general direction of the satellite to be tracked, reducing the amount
of cable wrap for your feed line. Remember to include a service loop
in the Coax to allow for the rotation and to account for the weight of
the feed system when balancing the antenna.
