Question

Can I Backfeed A Video Input On An Unused Coax Network

I have an RV and it's wired with 2 coax cable wall plates on the inside and one input jack on the exterior wall. My question, is it possible if I don't have a cable connected to the input jack on the outside of the RV, can I utilize the existing coax within the RV to carry the feed (backfeed from my A/V RCA jacks) from my new Stereo/DVD Head Unit and send a signal thru the coax system to the jack in the rear of the RV at my bedroom? The coax wall plate near the head unit is the one I would plug the coax wire from the head unit using a RCA/Coax Adapter at the head unit to feed the coax network but not sure if it could be read on the one in the bedroom by plugging the TV into the coax jack located there. I'm worried whether the splitter would allow the signal to pass thru to the other output line going to my bedroom. If not I would assume I would have to find and remove the splitter and insert a coupler to connect the wire running to the front of the RV to the one running to the rear which would make the outside jack unusable in the future to feed a cable signal from the Campgrounds to my RV. Does anyone know if any of this is possible and is there a work-around to having my cake and eating it too? I hope this question wasn't too confusing to understand........

Iffy but worth a try.

The cable coax (that antenna or cable feed) is usually 75 ohm and luckily same for composite signals. Read https://en.wikipedia.org/wiki/Composite_video about that.

So in theory it should be fine. Yes it can muck up the signal a little if the length is a bit long but that's expected.

Thanks But How About The Splitter?

Being an RV I don't expect too much length on the cables since the distance as the crow flies is only about 10 feet from jack to jack but I'm sure the routing from 2 way splitter to each wall plate is quite a bit more than that but I guess my biggest concern is whether the splitter which I have yet to locate would prevent the signal from flowing from one output connection to the other to be able to reach the bedroom. That's why I mentioned in the original post that once I locate the splitter I may have to remove it and just couple the two input cables together for it to work......

Will have to try it.

As I encounter so many different splitters I can't guess what you have in there. Best to just try it.
