When considering a stack of dissimilar VHF and UHF yagis, invariably, research will find that if a 6m yagi is involved in the stack, it will always goes on the bottom. My question does not pertain to stacking distance, but stacking order. Is the location of the 6m yagi on the bottom for mechanical, or for electrical reasons?
6m is my bread and butter band. It's the band that garners the most contacts and grids in a contest. But with my modest tower, limited in height, holding 5 bands, 6m, 2m, and 70cm yagis, a 23cm looper, with a 1.25m FM vertical on top of the mast, I'd like to place the 6m antenna at the top of the stack to get it as high as possible. But I'm concerned that I would be violating an unforeseen electrical law like beam pattern tilt or the 6m yagi acting as a ground plane of sorts to the other 3 bands. Any opinions?
