[TowerTalk] Beam spacing

[Tony Brock-Fisher]

I just modeled nearly the same situation - a 40-2CD 10 feet under a KT34XA. I found that at this close spacing, forward gain on the XA on 20 was down ~1.5 dB. High angle rearward nulls get filled in.

If I turn the 40 90 degrees, the problem goes away. You should be able to model this combination.

Of course, everything is a compromise. It's may well be  worth the loss in performance on 20 to get the performance on 40...
