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.

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).

adapter (not supplied).
