Hi OM,

There's a good chance it was from one of Walt's own many publications,
or it was, as he said, Dr. George H. Brown (the nominal, ultimate
source) with whom he worked.

My 1978 Antenna Handbook by Orr & Cowen, page 92, references drooping
radials at a 45 degree angle for a better impedance match, raising the
gain of the ground plane antenna by about 0.5 decibel over the normal
configuration.

'Course Walt probably preceeded those guys :-)

I thnk it predates 1978 by some margin. I may even be in one of the old
"Admiralty Handbooks", if anyone has a copy to hand they could check.

The explanation is a fairly standard one, although Walt does express it
well. If Walt is the originator of the idea I suspect he has a many more
turns on the coil than he is admitting ;-)
