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:
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 antenna.
• Connect an outdoor antenna cable lead-in to the COAXIAL CABLE CONNECTOR on the rear
of the TV set.
Antenna Connections
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). The F-type connector
should be finger tightened only.
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 ADAPTOR (not supplied).
