Default Connect coax shield to pipe when dipole is at top of pipe?
wrote:
I've long used an end-to-end pair of same-band hamsticks on a metal
bracket at the top of a push-up pole for a quick-and-dirty expedient
dipole. My support pole is usually wood, but when I put the dipole
on top of a metal pipe I realized there are two ways to do it:

The hamstick that is connected to the coax center wire
is always insulated from the pole, and the hamstick
that is connected to the coax shield could EITHER be
INSULATED or "GROUNDED" to the pole.

QUESTIONS: Which should it be? Should/Would it make any difference?

I suspect that connecting the shield would be better. Connecting the
shield and using a 1:1 balun at the top would be best.
