Yes. I believe it started with the question: "Has anyone ever actually
built a Lazy H for 10 or 11 meters?"

Although I`ve built many antennas for 33 MHz, a frequency assigned to a
company I worked for over a long period of time, none of those were Lazy
H`s. I have built many Lazy H`s for several other frequency bands used
for shortwave broadcasting but 10 and 11 meters are not assigned to
broadcasting. The Lazy H, with a plane of phased resonant reflectors
directly behind to make the array unidtrectional, is one of the most
popular for shortwave broadcasting. The highest frequency band I`ve used
is the 17 MHz band. Nothing significant will happen if the same 17 MHz
antenna is scaled for 29 MHz. In fact our shortwave antennas were
physically modeled at 450 MHz, before the first full-sized shortwave
antenna was ever built, just to prove the design. Measurements on big
and little antennas proved both to give the same results.

I`m inclined to believe the questioner made some mistake and there is
nothing wrong with a properly designed and constructed Lazy-H antenna on
any frequency.
