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.

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

OUTDOOR ANTENNA CONNECTION
