5 Setup Instructions Important Things to Note Before Starting Your Installation If you plan to use your own coaxial cable instead of the provided cable, you must use cable and connectors rated at 50 ohms. Although cable used for cable TV installations looks similar to this cable, it won’t work with your Listen system. If you need to run cable ove[...]

6 Setup Instructions Important Things to Note Before Starting Antenna Orientation 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 Ant[...]

7 Setup Instructions Important Things to Note Before Starting Selec ting an Antenna Location The location and conguration of your antenna mount will determine the quality of your signal; therefore, there are some important factors to consider. • Where will the receivers be located?

9 Setup Instructions Dipole Antenna Mounting Options 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 exible dipole (the oppy wires) in this conguration. Select the correct wires for your conguration (72 MHz or 216 [...]

10 Setup Instructions Dipole Antenna Mounting Options The antenna may be mounted to a mast, pole or section of vertical conduit. A mast made of non-conductive material works best; however, if you must use a metal mast, be sure to orient the antenna mount so the mast is not between the antenna and the designated receiving area. The Mounting Plate is[...]

11 Setup Instructions Dipole Antenna Mounting Options You have two choices of antenna with the dipole option: the rigid dipole, which has the two extendable arms, or the exible dipole, which has the “oppy” wires with securing rings at the ends. Rigid dipole pieces screw onto the connectors at the top and bottom of the Antenna Module. Flex[...]

12 Setup Instructions Monopole Antenna Mounting Options A monopole (single element) antenna may be mounted to a grounded light box or junction box in a ceiling or oor using the Mounting Plate and Mounting Bracket.
