ASTROPLANE best vertical antenna ever?

Picked up another ap original. I’ll have to rear it apart and clean it all up. Seems to be in good shape other than the nuts and bolts of course.

I may not mention this much, but I like it when people get these old original antennas and restore them. And this being one of my favorite antennas to explore...

Keep up the good work.

Does it matter if I isolate the mast from the tower? I’m at 50’ to the bottom of the skirt on a tower. Also wouldn’t I need a choke at the same place it isolated from the tower? Isn’t that like 9’? But just how much difference does it make if any
 
If you isolate it a little over 1/4wave below the hoop & choke the coax at the same point it reduces/eliminates cmc on mast & coax screwing up the pattern,

The DB made some models he posted on here with isolation at different distances below the hoop.
