Sorry, I wasn't completely clear in my post. The elevated radials are not connected to the buried radial field. They are two separate entities. Now the elevated radials do sit above or cross some the buried radials in some places so I'm sure they do interact but they aren't directly connected together.
I only have a finite space to work with and the tree limb I'm using to support the wire "is where it is". Everything I'm doing at this scale is a huge kludge or compromise but I'm just trying to optimize my situation as best I can. The BOG however sits nowhere near the radials. So, the 100' vertical has only ever been hooked to just the buried radials or the elevated radials at any one moment during my testing. I do have a common mode choke at (near) the feed point. It may or may not be effective at 160m. It does work on 10-80m. It is about 25' of RG-8 coax wrapped around a 4" PVC pipe as a form. Perhaps not ideal...
