Yeah, I'm getting a lot of "I'm confusing matters" this morning but wouldn't be surprised to find wi-fi and UHF (remote) to share antenna receivers or a common pickup point. I could be wrong but if someone knows things to be empirically different they're not speaking up so I do things the old fashioned way... trial & error. Nothing ventured, nothing gained. I personally wouldn't be at all surprised to find all onboard antennas to share a common pickup point then process different type signals at differing locations. But we have to start somewhere unless you can say empirically what I'm attempting is a complete waste of time in which case I'm happy to defer to you as that would mean you're positive while I'm a definite maybe at best. One of the quickest things I've learned with Devialet is just because something might seem counter-intuitive doesn't mean we should dismiss it summarily without at least independent exploration/confirmation.
