If you were clear up to 100 miles away or stuck in the woods 50 miles away, the Channel Master Parascope (4251) was the antenna you needed, to get any stable UHF and almost always with antenna-mounted preamplifiers. At least analog was giving us clues if it was multipath OR weak signal screwing with finicky UHF

The UK has been UHF only since Colour TV started in 1969 (vhf was 405 line b&w ended 1985). When we had analogue TV the main transmitters power was usually 1000kw per channel - any type of aerial/antenna for 100 miles even with a mast top amp sounds like a stretch here… i am sure others will correct me though… |

In studying the ghost conditions for digital, we had special receivers that could plot the ghost signals from the equalizer taps. Then you could draw an ellipse on a map representing all locations that would produce that delay. This is how we discovered that the Golden Gate Bridge in San Francisco caused trouble in certain locations that had a simultaneous clear view of it and the transmitter. |
