Cut the element as a DE and use a relay switched coil in the center. I'm
not sure how that works in the trees but that design does work as a DE/REF +
DIR/DE combo when the dimensions are stable.

Jim, have you considered switching the reflector to a director for long
path? Sounds like your stub switch might allow that.
I tried modeling that, and couldn't find combinations that made it work.
So the plan is drive the reflector and switch stubs into the other
dipole. Before I can do that, there are installation details, like
trimming the coax to the shortest practical length that still gives me
the height, replacing a blown Polyphaser, figuring out the coax length
to the panel, then doing the design on the basis of that length.
