Well Bruce/Me, /// 
It will surprise you, perhaps, to learn that there are many thousands of 
vertical HF and MF transmitting antennas in operation in the world today 
that satisfy none of those conditions, and yet enable effective 
communications activities. Some on land and some over water. These 
installations are supported by rigorous theory as well as by on-the-air 
performance data.

I see that he realises that airborne trailing wire antennas can work 
well at HF with just a tube fuselage as a ground reference - miles 
away from ground! 
 
This just about completely contradicts his earlier posts about ground 
references needing to be in close proximity to the ground for 
successful HF work, wouldn't you say?
