TV Antenna/Video Signal Combiner (150-1298) Features Faxback Doc. # 18211 Your Radio Shack TV Antenna/Video Signal Combiner combines a broadcast TV signal and a TV Channel 3 (15-1298) or Channel 4 (15-1299) signal (such as from satellite TV, a cable box, a VCR, or a video disc player) into one cable so you can easily tune to any program source using your television's tuner. It eliminates the need for a separate video selector switch. You can select the combiner that operates on a channel not used in your area. (CS/all-12/14/95)
