Antenna Connection

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 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).
OUTDOOR ANTENNA CONNECTION
• Use one of the following two diagrams if you connect an outdoor antenna.
A: Using a VHF/UHF combination outdoor antenna
B: Using separate VHF and/or UHF outdoor antennas
• Connect the outdoor antenna cable lead-in to ANT. (Antenna terminal) on the rear of the TV set.

F-type connector should be finger-tightened only.
When connecting the RF cable to the TV set,
do not tighten F-type connector with tools.
If tools are used, it may cause damage to your
TV set.
