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.

Upon signing cable subscriptions, through a single cable distribution, end-users need to choose between multiple incompatible receivers compliant with either a single unicable LNB or a Multi Feed Multi-satellite reception by Monoblock LNB in twin and quad versions, unless they intend to use two or four separate cables connected to alternative ...
The antenna is connected to the television with a specialized cable designed to carry radio current, called transmission line. Earlier antennas used a flat cable called 300 ohm twin-lead . The standard today is 75 ohm coaxial cable , which is less susceptible to interference which plugs into an F connector or Belling-Lee connector (depending on ...
Slotted array UHF television broadcasting antenna. As shown by H. G. Booker in 1946, from Babinet's principle in optics a slot in a metal plate or waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot, with the exception that the electric field and magnetic field directions are interchanged; the antenna is a magnetic dipole instead of an ...
Diagram of a beam waveguide antenna from NASA, showing the signal path (red). A beam waveguide antenna is a particular type of antenna dish, at which waveguides are used to transmit the radio beam between the large steerable dish and the equipment for reception or transmission, like e.g. RF power amplifiers.
A Unicable LNB has one output connector but operates in a different way to standard LNBs so it can feed multiple tuners daisy-chained along a single coax cable. Instead of block-downconverting the whole received spectrum, an SCR LNB downconverts a small section of the received signal (equivalent to the bandwidth of a single transponder on the ...
Here are the steps to take when you’re ready to break free from your cable TV service, starting with your current cable contract. Step 1: Check your cable contract. If you’re paying for cable ...
