I use fiberglas tubing for such.

You mean you get some fibreglass tubing and insert the element rods into it
from each end? I guess so.

Thing is I'm wanting to make a folded dipole element. Perfectly okay of

Anyway, I was investigating the casting approach, but it does not seem
common. Lot's of non casting ways. :c)
