I have a spare Stackmatch box, repaired after a lightning hit, and I'm
thinking about using it to let me simultaneously or alternatively feed my
40m yagi at 104 feet, a low 40m dipole running NE/SW at 25 feet, and a
medium-height 40m dipole running NW/SE at about 45 feet, in the hope of
filling takeoff angle holes for domestic contests. Before I build up the
control box, in case I've missed something, are there any reasons why this
would NOT be a good idea?
I'm aware that the yagi and the medium-height dipole could couple fairly
strongly at that spacing, when the yagi is looking the same way, but think
that most of the time the yagi will be perpendicular to that dipole. My
modeling of other stacks, when the two antennas are perpendicular, suggests
they basically behave like separate antennas then.
