PArdon me, but "Solid Pipe" seems to be a contradiction in terms ;-)  (Pipes 
are hallow)

Pipe?  Copper Pipe is intirely too heavy, and extremely large for V/UHF work!

I remember an antenna that was commerically made for 2m, by Cushcraft.  Had 4 
driven elements, and they were cross-fed, so the last DE to be fed, was 180ø 
out of phase.

It's been pointed out, it might be a bit cumbersome...  but a pair of 5/8 
elements as DEs and yagi directors does sound reminiscent of a Quagi.
