Wow!  John Brune and his sidekick John Gratalo are the guys that I ran 
into at Lakehurst NAEC in 1981 where they were flight testing the 
system. I didn't know that they were famous. When their project was 
done, John Brune kindly sent me a copy of their report AVRADCOM 
Technical Report 81-3).  The report includes details of the antenna 
design plus lots of NVIS flight test data.

in 1996 Worldradio published a NVIS book consisting mostly of reprints 
of articles from Army Communicator magazine by David Fiedler and Edward 

Even so, a lot of hams don't know about NVIS, perhaps because most ham 
publications and antenna literature emphasize low radiation angles for 
DX, rather than antennas optimized to cover a "service area".
