Epson Home Cinema System Note, Warning, Using an Outdoor FM Antenna

Using an Outdoor FM Antenna

A 75-ohm outdoor FM antenna may be used to improve reception. Disconnect the indoor antenna before replacing it with the outdoor one.

1Connect the antenna’s coaxial lead to the FM connector on the back of the AV controller.

2Ground the antenna system as shown to provide protection against voltage surges and built-up static charges.

Note

Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.

3If you hear audio hum or buzz as a result of grounding the antenna, connect a ground loop isolator to the antenna cable close to where it connects to the AV controller. This filters out interference caused by the outdoor ground connection. Or you can use a coaxial surge protector instead.

Warning

Never disconnect the antenna’s ground connection or disable the grounding pins on your power cords. These exist for the protection of both you and your equipment.
