Question regarding satellite signal through coax outlet

[rexmitchell]

Hi all, got our first travel trailer a few months back. 29 ft Cruiser Crossroad and we love it. Decided to get a king tailgater portable satellite to run when we are on the road. The dish won't be mounted so we will have to setup each stop. Now, my question is, what is the difference in the coax inputs on the outside of the trailer. I have one for satellite and one for cable towards the rear of the rig. I also have another input towards the center on one side, and one of the side with the door. My instincts tell me the satellite input is the one to use but what are all the others for? I also was warned that sometimes the signal from the satellite won't go through if there is a splitter or relay in the trailer. Any experience with this? Thanks for the help in advance.

Coax splitters have baluns which do not pass DC. DC voltage levels are supplied by the receiver to the dish to select the preamplifier heads (one per satellite).

Thanks. The outlet on the front of the trailer next to the door and with an outlet near it I also assume is an output just not sure from which input.

Your instincts are correct; use the satellite port. It should not have any splitters or filters on the line. The cable is obviously for cg cable. Not sure what the others might be.

Thanks. What is the best solution for this other than running the coax through the door out to the dish?

Very generally speaking you will not get a good HD signal routing thru the crappy coax and cheap splitters found in most RVs. You can test it, but dont be surprised.......
As a test, setup using a known good coax from dish directly to reciever. Get a good signal, then connect thru the sat in on the side of your RV. Signal? Or no signal?
