Antenna Orientation

Setup Instructions

Important Things to Note Before Starting

The antenna’s pattern is hemispherical, meaning that it has an “active” side and a ground side. The active side directs the signal toward the receivers, so it is essential that the active side be oriented toward the area where the receivers will be used. The Antenna Module’s ground side has the word “GROUND” molded into the plastic.

See Diagram A. If it is necessary to locate an antenna low on a wall, the ground side should face down. If you are mounting a monopole antenna in a ceiling or high on a wall, the ground side should face UP. It may be necessary to move the ground side of the antenna mount around in order to accomplish this.

To move the ground side of the module, simply remove the four nuts, reverse the module so that the ground side is facing the bracket, then re-attach the nuts. Be careful to not detach any wires if the module opens while it is not secured to the bracket.
