It is a little interesting that at 50 foot height, the pattern of a single
6600 foot center-fed wire has a single clean lobe on axis and the low angle
gain is quite high.    Might be uselessly narrow beamwidth, but if you have
the room to support the huge loop, you have room to point it at your last
needed zone :)

I do remember a QST article a while back about someone who put up a huge vee
beam to inexpensively get high gain in the direction of their last needed
DXCC entity, or something of that sort.  Sometimes point-to-point antennas
are worthwhile.

All in all, though, seems like a lot of work for little return for general
hamming.

Ha!

Is he flying true north?
