Antenna Connection

ANTENNAS

•The antenna requirements for good color television reception are more important than those for black & white television reception. For this reason, a good quality outdoor antenna is strongly recommended.

The following is a brief explanation of the type of connections that are provided with the various antenna systems.

F-type connector

1.A 75-ohm system is generally a round cable with F-type connector that can easily be attached to a terminal without tools (not supplied).

2.A 300-ohm system is a flat “twin-lead” cable that can be attached to a 75-ohm terminal through a 300-75-ohm adapter (not supplied).

75-ohm coaxial cable (round)

300-ohm twin-lead cable (flat)

OUTDOOR ANTENNA CONNECTION

•Use one of the following two diagrams if you connect an outdoor antenna.

A:Using a VHF/UHF combination outdoor antenna

B:Using separate VHF and/or UHF outdoor antennas

•Connect the outdoor antenna cable lead-in to ANT. (Antenna terminal) on the rear of the TV set.
