I don’t have software to model this scenario. Can I install a F-12 mag 520, 6.5 feet above a F12 340N, without the 2 x yagis interacting?
The 520 is a 5 el 30m yagi on a 35 ft boom. The 340N is a 3 el 40m yagi also on a 35 ft boom. I wont attempt it if the 20m yagi gain drops
a few db.
It still baffles me how some xmas tree monoband stacks require huge vertical spacing to eliminate gain redux, screwed up FB, yet F-12, optibeam, JK ants, N6BT, all sell
interlaced arrays, covering 2++ bands on one boom. Im not talking about forward stagger designs..but stuff like the C49-XR, etc, which is clearly interlaced.
Tnx... Jim VE7RF
