I don't believe the left and right element sections are supposed to make contact with each other.

FWIW, this does not appear to be a log-periodic, but rather a Yagi-Uda style design.
Yes the only element that I connected to the plastic housing [rotor] is the medium loop.

I have found 2 antenna pictures [China] that are similar I'll attach them. One seems to have its long element behind the big reflector. These photos don't help me though.

I found the following reference on Yagi-Uda style antennas. Seems very much like mine except the article example uses single pipes where I have loops.
http://www.antenna-theory.com/antenn...lling/yagi.php

It calls the only active element a folded dipole and calls the element in the back a reflector. The other elements are called director elements by the article. It doesn't speak about a element in the very back like mine[the wire mesh circular one].

I think that with your reply and the technical article I know what to do with
The small loops [directors], the medium feed loop[folded dipole] and the large loop[reflector].
THANKS
