RCA has a short-run, flat co-ax which it says is "perfect" for connecting inside and outside cables for satellites under windows, etc. BUT, it doesn't mention if its RG6 or not. A google search turned up some combination wire (coax, phone, networking,etc. called "ribbon", I think), but I think that's a little much for me. I seem to remember hearing about a device you attached to each side of the glass (in my case, a sliding door) and it passed the signal through. Is this still around, or was it a bad application that has since died? Anyone have any ideas? Thanks!
