I should have said "the more RF chokes there are, the less current will
flow in the center conductor of the case where the wire is inside the
shield" by the way.

If the RF chokes and wire are inside the shield, it will keep the
current off the wire inside the shield.

However, where the wire exits the shield, currents can still be induced
on it... this is what allows current to flow on the unchoked center
conductor, right? So why wouldn't it flow in the other direction.

So you need chokes some distance outside the shield to isolate the rest
of the wire from the antenna.

If you put the wire outside the shield and put chokes at the top and
bottom, some distance away from the antenna, then a very large current
will be induced on the wire between the chokes compared to the current
you get on the wire inside the shield. However, this doesn't
immediately translate into more current on the control wire trailing
away. It is just saying something about the wire between the top and
bottom chokes.

What you're trying to do is decouple the control wire going away from
the antenna from the antenna. Decoupling the control wire that runs up
inside or outside of the antenna isn't very important as long as
current doesn't flow on the control wire to the shack.

Whether or not inside or outside of the tower/tube helps depends on a
lot of factors and should be answered with some sort of calculation...

Seems that the various claims are testable...

I'll post anything I come up with.
