Dan:

Some of these arguments carry on into the realm where I lose interest...
but right on when you say, "...put a choke on that sucker!"

This may be due to the fact that I am not an "antenna guru" and can't be
certain when one is best, and when not... so what? Make fun of me
then!!!
tongue-sticking-out-grin

Warmest regards,

I was hoping we would not have to go through this AGAIN.

The typical J-Pole (Closed Stub) was designed to feed with open feed
line. Because Hams insist on feeding it with coax, a Band-Aid is
needed to choke off feed line radiation & common mode currents.
The Open Stub J-Pole was designed to feed with coax. So it don't need
the Band Aid.
The difference between the two is discussed in several antenna books.
Just ask anyone the owns one.

Besides your the antenna expert, tell us why it would.

For exactly the same reason that you need a choke on a ground plane or
any other antenna feed with coax. Depending upon the length of the
feed line common mode current can be substantial. This, in turn,
increases higher angle radiation. Now if you are most interested in
talking to airplanes that would be a good thing, but if you prefer
maximum signal towards the horizon then put a choke on that sucker!
