Channel Master is one of the few television and FM radio antenna companies that has survived the evolution from over-the-air (OTA) broadcasting to cable-based and then Internet-based broadcasting. Up until around the end of the last century - which is incredibly two decades ago - a large number of people still relied on rooftop and set-top antennas for program reception. Airwaves continued to get more crowded both due to additional stations being built and the ambient noise level increasing due to many other lower power devices in use. An increasing number of manmade obstacles that blocked and/or reflected signals resulted in many more low signal strength pockets and areas plagued by multipath signal variability compounded the problem. High efficiency antennas with high directivity became more in demand, and often a rotator was used optimize reception. I find myself using the vintage Alliance Model U-100 Tenna-Rotor to redirect my Channel Master CM-5020 antenna to avoid interference from nearby (in frequency) stations that can come in from Toronto, Cleveland, and Buffalo. According to news stories, the worldwide "cable-cutting" trend is being accompanied by a lot of people installing supplementary OTA setups. It's nice to see antennas popping up again - even if most of them are the compact type with integrated preamplifiers, similar to my Able Signal Amplified Digital Outdoor HDTV Antenna .
