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 more than 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 .
