I think you may be kidding yourself...
a Y-ending for the shield vs. the center conductor CAN be waterproofed
with the usual tapes and goops, and the resultant termination...
This termination also will not have the inherent loss and potential for
failure that your connecotr(s) will....
On my three high twenty meter stack all the coxes rum from the feedpoint
(where there is a waterproffed "Y" to the base of the tower where they
are terminated with PL259's - which then screw into a Stackmatch.
Having had failures of connectors and barrels more than once my current
thinking is the fewer of these there are the few chances there are for
failure down the road.
Currently I am working on another stack of antennas and do ope to do the
same - run the coax from the split driven element feedpoint directly to
the ground WITHOUT any intermediate fittings....
To those who have thought about the downside of this, yes you must
disconnect at the feedpoint of the driven element should you have to
lower the antenna....this was no problem on the 204BA's driven elements
which were easily within reach from the tower...current project has the
driven element some 11 feet or so away from the center of the
antenna....will necessitate some sort of tilting of the antenna to
disconnect the feedpoint. At instalation time the element can have the
coax attached and the coax unfurled from topside...when it is time to
take it down however the prospect of un-taping the feedline from the leg
would indeed be a hassle, hence tilting would be needed then.
So far the the twenties are clicking just fine after about 4 or 5 years
- knock on wood!
