PREPARATION (Continued)
• 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 F4ype
connector that can easily be attached to a terminal without
tools (not supplied),
2. A 30O-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).
F-type connector
75-ohm coaxial cable (round)
300-ohm twin-lead cable (flat)
