Nonsense. For research purposes, just put up a balloon vertical on a
calm day in some remote area. Set up a transmit source a mile away and
compare received signal strength vs height. Temporarily roll out some
radials. I could do this test at my own QTH of 20 acres and I'm no
Warren Buffett (land is cheap where I am). I could test the balloon
vertical over my big ground screen and then move it away from the ground
screen and retest. Maybe someday when I have the time...
BTW, the complete Proceedings of the IRE back to before 1920 are
online at the IEEE now. Laporte's book is now available as a pdf.
