Does anyone know how to stack 2 or more Hy Gain 105CA, 5 element 10 Meter beams?
Thanks,
Mike

Mike:
Simply space them about one half wave apart and feed in-phase (using equal lengths of coax). If you use one of the commercially made switches, you will have more flexibility, as you will be able to feed either of the antennas by itself or both together.
Good luck.

I would stack them at least 25-30' apart. I use 3 KLM 610's which are on slightly longer booms (27.5' versus 24') and they work well with 35' spacing. I believe the Hy Gain antennas use baluns so be careful that they are both polarized the same way. I used YO7 to optimize the dimensions of mine in a stack and you can see the difference here:
