LPL told me one time that his best antenna is a large 10 M Yagi at 200'. He theorizes that when you get an antenna that high, in terms of wavelength, the nulls fill in and become almost non-existent.

That's interesting. On my 6/6 on 20m @ 140 and 70 feet I usually see little difference between lower, upper or both. When there is a difference the top is usually the better antenna (even to U.S. sta
LPL impression is confirmed by also my own, although I'm convinced that 10m benefits of very low angles much more than any other HF band. At IR4T we have infact a 10m yagi 7WL over a nearly perfectly
IF this data is the same as N6BV published in the ARRL Antenna Book, it ASSUMES antenna heights of 100 ft for 80 through 17 meters and 60 ft for 15, 12, and 10M at BOTH ends of the path. Naturally al
One can also look in the Archives. I believe there have been posts from people telling of their observations at larger stations of what they were hearing at particular times, and which antenna setup
That seems quite plausible since the lobes and nulls become VERY NARROW at 6 WL high :-) First Lobe 1 to 3 degrees Second 6 to 8 Third 11 to 13 Fourth 16 to 18 Fifth 21 to 23 A small ground slope of
Your 20M antennas at 70 and 140 ft are 1 and 2 WL high respectively, not really what I consider to be a low antenna on that band. The 140 ft beam has a second lobe from 19 to 25 degrees and is 5 dB o

Do I need 30 degree coverage? According to the ARRL's YT data received signals in my area from Europe over 20 degrees happen 0.7% of the time, from South America 0% and from Japan 0% of the time on 2
