I have a 21 element 70cm beam with the driven element completely removed. I'm
trying to determine the manufacturer and more importantly how to reconstruct
the driven element. I would like to replicate the original design but if all
else fails, I'll design one myself. I suspect that it is made by Hygain
because the Hygain 70-31DX has several similar features.
This has 21 elements total, is about 190 inches (16 ft) long. The elements pass
through the boom and are held in place with 1 screw each that is screwed into
the boom; so the elements are not insulated from the boom. The mast mounts to a
clamp that has a U bolt that passes through the boom. The boom appears to be
completely self supporting (no overhead supports).
Can anyone help identify the make / model or the original driven element design
??
