OOPS. Forgot-the bottom of the quarter wave sleeve choke needs to be connected to the shield.

In a multi-band J-pole (where higher frequency j-poles are basically
mounted on the long leg of the next lower frequency leg) can the feedpoint
chokes for all the bands be located at the base of the antenna, or do they
need to be kept right by the J's for each band? The "copper cactus" has
the feeds running up the center pole and poking out holes in the tube
for each feedpoint. That would require putting the chokes at the base of
the mounting stub.
