[Boatanchors] B-17 antenna connection

[Michael Hanz]

It certainly has a lot of similarities, Nick.  The primary difference is 
that the tower is in the normally desired vertical radiating plane, and 
the rather complex aircraft skin topology is primarily in the horizontal 
plane.  We all know that horizontal loops can be pretty decent radiators 
and detectors, since a number of folks have such loops around their 
properties that seem to do pretty well at HF frequencies.  Walt Hutchens 
KJ4KV had one around his house that seemed to drag in a lot of stuff I 
could never hear on the weekend mil surplus net, and I never heard 
anyone complain about his signal strength.  I'm not enough of an antenna 
expert to intelligently comment on the Boeing arrangement, but its 
apparent use on more than one of their aircraft suggests it had some 
following.
