What about the ITU web site which has stuff on HF broadcast
antennas...Granted, most HF broadcasters probably use curtain arrays or log
periodics, but certainly, rhombics and the like were popular a while back.

You also might need to look a ways farther back than the last 20 or 30
years.. I'd look for papers in the 30's and 40's, when HF teletype and
voice links were a way to do intercontinental comms, particularly in the
Pacific. That's when serious money was being spent on understanding
various antennas....and, they probably had teams of guys (it WAS the 30's
and 40's after all) out making field strength measurements and building
these sorts of antennas.
