Hello, Roy & the Group.

One think you may have missed, the original post was about a Arrow
Antenna J-Pole. This is an Open Stub type J-Pole, Not a Closed Stub
type like the copper pipe ones. The OSJ does not need a choke, it does
not have a problem with feedline radiation or a problem with Common
Mode Currents.

In the typical J-pole antenna, the shield connects to the long element
and the center to the stub.

I've read, in this group, it doesn't matter which side the center
connects to. That's not true?

don't know your antenna in particular,
but I would suspect this is the case and don't believe it is considered
a radiating element.

The OSJ is not a typical J-pole.

By open stub, you mean there is no loop at the bottom of the "J"?
