"That's because at frequencies above 14 MHZ, it makes a nice cloud warmer.
The higher the
frequency, the warmer the clouds get."
Well, that depends on your definition of cloud burner. The 43-foot vertical
provides performance >= most commercial verticals up to about 15 meters.
However, on 10 meters it is about 5dB down from a ¼-wave vertical at 10
degree take off angle. But the 43-footer has a higher radiation resistacne
so ground losses are lower so this compensates some. Here's a good analysis
