In QST for September 1995, Brian Beezley, K6STI, had an article titled "A
Receiving Antenna That Rejects Local Noise" and Ed Andress had a companion
article, "A K6STI Low-Noise Receiving Antenna for 80 and 160 Meters." This
antenna, a horizontal square with a twist in the middle, has a very high-angle
pattern. It rejects local noise by having barely any of its pattern at low
angles.
Here's what Andress said: "I compared my DX reception with the local 160-meter
Big Guns daily and found that I could copy all the signals they heard, but for
a shorter time during the window." In a sidebar, Keith Fowler, W6BCQ, reported
that with the horizontal square, he was able to work C21/ZL1AMO; on his other
antennas, he could hear only power-line noise. My experience with this
antenna, before I was licensed, was that I could hear audio from some
Indonesian regional broadcasters that were only weak hetrodynes on other
"low-noise" antennas.
Beezley himself acknowledged that if you've got the space for it and there
isn't a strong noise source right off the end, a long Beverage is a better
choice. And since July 2000, when K6SE wrote about flags and pennants, most
people looking for a good low-band receiving antenna that will fit on limited
real estate have used flags and pennants, and I think Beezley's antenna has
been largely forgotten. But his antenna clearly demonstrated that some good DX
is possible with antennas that offer only a high-angle pattern.
