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
Farmer.
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".
