We found out our main cable entrance wire was bad... would deliver an ok picture on higher channels - very snowy on lower... but really showed up when we tried to use high speed internet - modem wouldn't detect any signal.
Tech tried getting a tone across the cable from entrance to distribution box - and nothing... (That won't work thru a splitter - but I can't see a reason for a splitter having been used in that run..)
I don't see any good way to run a replacement inside the RV (video distribution box is front passengers side - and external cable jack is rear drivers...) so thinking to drop down from the cabinet thru the floor (cover wire with molding where visible) - run the wire under the rig in plastic loom from front to back - then come back up through the floor behind the bedroom cabinet and to the rear of the exterior jack (visible with drawers out...)
Open for better suggestions - I haven't come up with one yet...
In the meantime using a wire from the cable box coming thru a window... but the hard rain will have me moving it to come in under the slide until I get the new cable, loom, and molding...
Here's what I'm considering using:
(this is 5/8 but out of stock.. might go to 1/2 or try to find locally...)
