I was thinking more of the case where your coax gets from tower to shack 
at ground level or in conduit.

for the case where you leave the tower at some height and, say, go 
across to the house at some height, I don't know.  Put a bulkhead 
connector panel at the point where you leave the tower?  No matter how 
you do it, you're going to have a loop of some sort formed by the 
shields, the section of tower from tie point to the ground, the ground 
between tower and house, and the coax entry point into the house.
