[TowerTalk] Need info on stacking some yagi antenas

[Phil]

I'm putting up a crank-up tower with a TH7-dx on
it.  I'd like to add a 6-meter yagi and a 2-meter
yagi above that.  Can anyone suggest a proper
spacing for these?  Should the 2-meter be on
top or in the middle?

Thanks for the help, 73, Phil  W5BVB
