PREPARATION (Continued) 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). F-type connector 75-ohm coaxial cable (round) 300-ohm twin-lead cable (flat) 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. A.
