Channel Master's original product was a prefabricated television aerial with hinged elements which would unfold and snap into place; this patented design greatly reduced installation time as existing antenna designs at the time had to be bolted together from multiple pieces by rooftop installers.

The antenna used for broadcasting through the 1920s was the T-antenna, which consisted of two masts with loading wires on top, strung between them, requiring twice the construction costs and land area of a single mast. [1] (pp 77–78) In 1924 Stuart Ballantine published two historic papers which led to the development of the single mast antenna.

This had a diamond (rhombohedral) shape which made it rigid, so only one set of guy lines was needed, at its wide waist. The pointed lower end of the antenna ended in a ...
A new mast was built around 1983 to replace the original structure, primarily to support new mixed-polarisation FM antennas. A 788-foot (240 m) tall temporary mast was erected alongside the 1983 mast in the spring of 2009 while the latter's height was increased by 100 ft (30 m) to 887.5 ft (270.5 m).
Guyed masts are frequently used for radio masts and towers. The mast can either support radio antennas (for VHF, UHF and other microwave bands) mounted at its top, or the entire structure itself can function as a mast radiator antenna (for VLF, LF, MF). In the latter case, the mast needs to be insulated from the ground. Guyed radio masts are ...
