And you're also correct about Richard Clark's statement. Perhaps he is
indeed attempting to do some MF broadcasting to his local
area -- I just assumed he wasn't.

I did, too. But antennas carefully developed and documented for good MF
broadcast performance also are useful for 160 meter ham applications.

And as far as significant radiation at elevation angles below 15 degrees,
Richard Clark might have allowed for systems operating above 30 MHz, which
include several ham bands, I believe. Use of these bands often is
line-of-sight between terrestrial endpoints, and would not be very
successful if all antennas had low relative fields near the horizon--as
implied by Richard Clark's post. FM and TV broadcasting and public service
radio (police/fire etc) use such low-angle radiation successfully, and so do
ham radio operators.
