"Multipath" reception is visible as multiple impressions of the same image, slightly shifted along the width of the screen due to the varying transmission path. Some multipath reception is momentary due to road vehicles or aircraft passing; other multipath problems may persist due to reflection off tall buildings or other landscape features.
Walt Disney Co.'s KABC-TV Channel 7 station, which uses communications towers near Mt. Wilson, lost its over-the-air signal Friday morning as the Eaton fire continued its rampage through ...
With UHF's reputation for reception problems, the fraction of new TV receivers that were factory-equipped with all-channel tuners dropped from 35% in early 1953 to 9% by 1958, a drop that was only partially compensated for by field upgrades or the availability of external UHF converters for separate purchase. Plummeting inclusion of UHF tuners ...
A broadcast signal intrusion is the hijacking of broadcast signals of radio, television stations, cable television broadcast feeds or satellite signals without permission or licence. Hijacking incidents have involved local TV and radio stations as well as cable and national networks.

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 region) on the back of the TV. [6] To convert the signal from antennas that use a twin-lead line to the modern coaxial cable input, a small transformer called a balun is used in the line.
It is easy to align and simple in circuitry. It was such a good design that it is still being used today in the Integrated circuit form. After the detector, it goes to the audio amplifier. Image synchronization is achieved by transmitting negative-going pulses. [l] The horizontal sync signal is a single short pulse that indicates the start of ...
