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 F-type
connector that can easily be attached to a terminal without
tools (not supplied).

adapter (not supplied).
