Monopole Antenna Mounting Options

Mount to a Grounded Electrical Box, Ceiling or

A monopole (single element) antenna may be mounted to a grounded light box or junction box in a ceiling or floor using the Mounting Plate and Mounting Bracket.

BEFORE STARTING, reverse the Antenna Module on the Mounting Bracket, then install the Hex Kep nut on the ground post (see Diagram G at right). The combination of the Mounting Bracket, nut and your grounded electrical box provides the required ground for the antenna.

If you do not have access to a grounded box, you will need to attach a flexible antenna element to the ground side of the Antenna Module (see Diagram I). Be sure to use the correct length element (longer wire for 72 MHz, shorter one for 216 MHz). Connect the wire underneath the shorting nut and run

it up into the ceiling.
