• 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).

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).
