Very impressive work, Dave! Doesn’t matter if AI wrote the code. You were the
brains behind it.
When I first read your post I thought perhaps you were going to use a couple of
dipoles end to end with rope between them for the antenna and was surprised to
see the dipoles on a boom. Would that not present some problem with the
coupling between those dipoles in the same plane with one behind the other?
