The Channel Master 4251, a high-performance parabolic UHF television antenna, stood about seven feet in diameter. Channel Master also built distribution amplifiers for cable television, satellite dishes and satellite antenna accessories. The Channel Master brand and trademarks are currently owned by a Delaware corporation which markets terrestrial television antennas and digital video recorders in Gilbert, Arizona. While the market for antennas has been diminished by widespread subscription television deployment in the post-network era, the Channel Master name remains in active use as a terrestrial television antenna brand, marketing IPTV and digital video recorder equipment to cord cutters seeking lower-cost HDTV.
