This gives me a new way of looking at the Isopole antennas. I am
begining to think the upper sleeve is not there for isolation but
rather it is a radiator and the bottom sleeve is there to decouple it
from the mast and feedline.

Thats it.. The upper cone is appx 5/8 wave and is the lower element.
The lower cone should be appx a 1/4 wave and is for decoupling the
line.
