I believe the hybrid would be reciprocal on receive (correct me if I am
wrong on this) in which case you could listen to the close-in stations
to get an idea of how much fill was provided by the high dipole. Also,
with a relay or two you could easily configure a switch that would
select between 4-square w/dummy load dump termination, 4-square with
high dipole dump termination, and high dipole direct. That would be neat
to play with.
BTW, I enjoyed your presentation, Dean. I always come away with good
food for thought after hearing one of your talks.
