[TowerTalk] Interlacing 2M elements on 6M yagi boom

[Bill VanAlstyne W5WVO]

I have an 18-ft 5-el 6M yagi (two of them stacked, actually). This system is an excellent performer, and I don't want to screw it up... BUT, I'd sure like to interlace a couple small 2M yagis with the 6M elements on the same booms. Feeding the 2M DEs separately from the 6M DEs is fine. The spacing between the yagis on 6M is fairly close (half a wavelength), so the 2M spacing will be about 1.4, not at all a bad number. I know I am going to have to get into EZNEC to learn how to model this kind of arrangement, but I thought I'd ask first -- is this feasible? Is it a good idea? Am I just asking for more headaches than it's worth? Since these antennas are on a guyed rotating mast on a 4-ft roof tower, I don't want to add any more weight and wind load to the system that I have to; otherwise, I'd just put a pair of stand-alone 2M yagis between the 6M ones. Ideas, opinions?
