With regard to diversity reception on bands other than 160m -- When 6-meter sporadic-E is very intense and present over a fairly large area between two stations, a phenomenon occurs where the signal will come in alternately at a higher angle and at a lower angle, fading back and forth, on average, every second or two. I've confirmed this by switching back and forth between my high/low yagi with the StackMatch while receiving such a signal.
I look forward to that "someday" when I acquire a KRX3 and can try diversity reception on 6 meters. The configuration would be my vertically-stacked 6m yagis each feeding a separate receiver directly. (And of course driven through the StackMatch on transmit, as they are now.) The exact physical model of sporadic-E propagation that is causing this phenomenon is open to some debate, but it is clearly happening -- when the Es is active and complex enough to support multiple-angle paths. Using diversity reception from a two-stack of identical yagis sounds very intriguing, and would certainly work just as well as feedline-combining even when this Es phenomenon isn't occurring strongly.
