The antenna may be hidden inside a wall or ceiling. IMPORTANT: Do not install the antenna inside a metal wall or ceiling, as this would obstruct the signal.

You will use a flexible dipole (the floppy wires) in this configuration. Select the correct wires for your configuration (72 MHz or 216 MHz). Connect one antenna wire to the ground side of the Antenna Module using one of the Hex Kep nuts provided. Connect the other wire to the active side using the other Hex Kep nut, as noted in Diagram D below. If you are using a Mounting Bracket, you will need to install the provided fiber washer between the antenna and mounting bracket.

Secure the mounting bracket to a beam, making sure the active (non grounded) side of the antenna is directed toward the area where the receivers will be located (see Diagram E below). Then, secure the ends of the antenna to beams using wood screws or the provided sheet metal screws. Try to make the wires as straight as possible, and make sure they extend in opposite directions.
