The Idea was to have a tribander in each tower, in the other tower
There will be a stack for 20 at 118'/90 ft and a c3 at 50 ft.
Since the c3 is small it fits fine between the guys but in the 15 mtrs tower
I don't have
Room to fit the tribander since the skyhawk is considerably larger.
I just hate to leave out such an incredible performer, this is the original
Back to the drawing board.

This idea just occurred to me:
One way to do this might be to put a stacked antenna matchbox up there that
would select "Upper," "Lower" or "Both" antennas and one could drive both
antennas in phase on 15 meters. The 15 would probably need a similar feed
system to the tribander to ensure they are fed in-phase and there might need
to be some re-tuning done on the antennas due to their proximity.
