What are folks using for their two antennas to provide improved reception on 160m?
I'd guess as many options as there are stations. :) It all depends on what is available.
Remember that one of the major reasons for diversity is that the antennas be spatially separated from each other to neutralize the effects of selective fading. When we receive both a direct and reflected signal from the DX station, the two arrivals can be more nearly in phase at one antenna location when they are more out of phase at the other antenna. That's not the only reason for diversity, of course, but it's a major one.
Some hams believe that differently polarized antennas should be used, or that one antenna have a high angle major lobe and the other have a low angle major lobe. Some of the best 160M ops I know rearrange their stations for 160M events by bringing all of their antennas to a big patch panel so they can switch between them to RX any signal that they're trying to work. It is well known, for example, that signals for a given path may be high angle at one part of the opening and low angle at another time.
