Here's a website which I was referred to when I had questions about stacking identical yagis horizontally and vertically, and vertically stacking antennas for separate bands. It's a start....hope you can some useful info from it.

I need some antenna advice. I ended up with two Elk and two Arrow beams. I thought about using two of the Elk antennas on a boom stacked horizontally. Would this be worth the effort? I am a little unsure about how far apart they would need to be to perhaps have some added gain. Seems like I remember seeing a photo of someone with a couple of the Elks mounted horizontally. I have a Cushcraft or a M2 coax divider that could be used. Am I just farting in the breeze or would it be worth the time to put the antennas together? BTW, I always put my antenna on a tripod while working the satellites. I am not a very good "one armed paper hanger".
