[Milsurplus] Tree Antenna

[gl4d21a at juno.com]

It's an idea which surfaces every generation or so.  Last hard 
documentation I saw was an SRI International project during Vietnam.  
George Hagn was the princioal investigator.  Probably appeared in one 
of the IEEE group transactions.

While I was sorting the DF files for dispersion a couple of years 
ago, I saw a Signal Corps report on tests of the idea in Central 
America during WW2, but made no notes of the details.

Since before WW2, the same concept.  Find a tall live tree with a 
good wet cambium layer, located out in the open preferably.  Drive 
two spikes in, one at ground level, one as high as convenient to 
reach.  Connect antenna tuner, adjust and go.  As observed, not very 
efficient, but that's what they made 30L1s for, isn't it?

73,
