For those unfamiliar, it is a horizontally-oriented loop antenna, one wavelength at fundamental, which is resonant on all (not just odd) harmonics. It appeared in Nov. 1985 QST and in the Handbook. Just wondering whether anyone has comments on its performance...

I could point a 15 dB. gain antenna directly at a 5 Megawatt UHF station less than 20 miles away (clear line of sight) with no amplifier overload whatsoever.

I would sugest >getting a good high gain antenna rather then spending your money on an >amp, because the fact is: if a tv signal is below the noise level, no My experience has been that antenna mounted amplifiers are extremely beneficial especially at UHF. Yes, the $7 Radio Shack ones that are really intended for cable are junk. But the ones Wineguard sells that fit into the built in housings on their antennas are excellent, although the 4 dB. NF could be improved upon with a homebrew GaAsFET amplifier. I paid $35 for my Winegard amplifier and it doubled the number of stations I could receive. It also allowed me to use my crummy VCR UHF tuner instead of just the good tuner in the TV set. By the way, I was already using Wineguard's top of the line UHF- only full band antenna (15 dB. gain, 12 foot boom) at 70 feet.
