Yes I do, but it is true, I do have limited wife access these days!
I am now home from Canada, and started yesterday on coach issues, one of which is the RTI Antenna. Mine is not located in the PS side overhead console where the RTI RP-6 processor is located. My schematic shows one antenna as part of the system, and recommends for best results locate in the middle of the coach and away from any 120 volt source. In tracing the wire for the antenna, it travels into the Audio Visual cabinet, and then up above the roof. I gained access to the rear of all the consoles up in the front of the coach, to no avail, but will continue my search.
It was described by RTI technical support as about the size of a pack of cigarettes. See attached for schematic. I will try to track down some other support people.
Once again, thank you, and any help would be appreciated.
