Two places now (Sandpiper Aerials and JB Television Services) where I've
made enquiries about dipole center peices and the only thing offered is for
1/2" tube. Small sample I know, but what, nobody makes dipole peices for
1/4" and 3/8" tube anymore?

I could always make sleeves I guess.

Many use welding rod for elements on VHF/UHF antennas. It's a good size.
You can build VHF yagi's totally from hard drawn copper tubing. Boom,
elements, gamma match, the whole thing. One piece, all welded together.
My 6m yagi is built that way from 1/2 copper for the elements. One inch
copper for the boom. Elements are brazed to the boom. I'd use much
smaller for VHF. You can get both 1/4 and 3/8 copper tubing. You could
use 1/2 inch for the boom. You want to use hard drawn copper. Preferably
not the soft stuff that is coiled. Although for VHF, even it would work
ok. But my 50 mhz yagi, I had to use hard drawn. It's too big for soft
copper. It would wilt... MK
