I neglected to mention that the center of the dipole
is welded (heli-arced?) to the boom, and one of the two
"folded" ends is also welded to this boom a couple of 
inches away from where the center  is welded.

This leaves the other end of the folded dipole as the
feedpoint.  The diameter of the dipole material is about
half an inch.  The boom material is about an inch.

I appreciate the comments so far, and apologize for
not being a little clearer with my earlier description.
