INSTALLATION

The receiver and antenna use TV Type F coaxial connectors.
The antenna can be plugged directly onto the receiver or 
mounted to a bracket and connected to the receiver with Model

Select a location for the receiver which allows access to the 
terminals and space for the antenna (as far from metal structures
as possible and preferably with the antenna in an upright 
position). Fasten the receiver securely with screws through the
two holes provided in the cover flanges.
