[BC] Long wire antenna

Sorry, Barry and all.  I don't know what happened, but my first link didn't 
work when I first tried it from within my BC post, and later on it 
did/does.  I won't use Filebeam again (that was the 1st time I did)

Feeding a horizontal long wire 150 m above the earth without radiation from 
any vertical conductor(s) to the earth would be a neat trick, and the 
antenna would have no useful  v-pol in the horizontal plane.  Not a very 
good MW radiator.

But ignoring all that I modeled 100-wavelength long wire in NEC, fed at one 
end by an embedded source (no vertical wires).  It showed a large number of 
lobes/nulls (>70); not pretty.  I won't bother posting it.
