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".

Thank you. And since it was used for tactical communications in combat
it probably was essentially classified for a while. Known only to US DOD
and friendly forces by that name, though the concept was known long
before Nam. Likely FM24-18 and training circulars of that era were also
not public documents for the same reasons. Which kept the name out of
vendor's catalogs until Brian Collins' paper in 1988.
And we should remember that any antenna deployed works better than one
left in the box.

Jerry,
Following extracted from a discussion on the Yahoo NVIS discussion group:
"I believe George Hagn was the
first to use the term, "near vertical incidence skywave" in 1967 and
Sol Pearlman at Ft. Monmouth to use the acronym "NVIS" in 1973 or 74.
However, it may have been John Brune at theFt. Monmouth Antenna
measurement range who designed the Transline Antennas for Army
helicopters"
