[TowerTalk] Combining antennas

[Pete Smith]

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.
