4. Mount the power divider on the back side of the outrigged mounting pole, as shown below, or to
another tower leg behind the antenna. Coil the cables in the vicinity of the power divider INSTEAD OF
looping them up and down the pole. This will minimize the interference of the power divider and cables
on the performance of the antenna.
