Satellite TV hookup

Good Job! Have fun.

Ok thanks for the help. I located the problem with a connection under the tv where it come in from the outside.

RoyB does not know how your trailer is hooked up as he does not use satellite and has not in many years.
Your coach is wired specifically for satellite and it absolutely CAN be used to connect your satellite antenna. It is a dedicated line that runs from outside to inside with no other connections or splitters involved.
Additionally, someone mentioned copper clad coax. That will not have any effect on the satellite connection either at the short distances involved here.
I would start by working backward. Start by connecting the receiver to the TV while inside and verify that you are able to get a clear picture from the receiver to the TV (no snow) even though all you will see is the Dish Logo bouncing around. If you can get that, connect the TV with the same coax to the inside port that should read Satellite and then connect the receiver to the outside satellite connection and you should again see a perfectly clear bouncing Dish logo. If that does not happen the coax cables may be reversed or mis-wired from the factory. Try the other connection just for grins. If none of that gives you the clear picture you should get then it's most likely that just the end connectors of the cable need to be replaced but if fixing those does not fix the picture the manufacturer may have run a staple through (or cut) the coax somewhere. If that's the case you are going to need a new cable. Worst case you can temp. run a coax through the slide seal or a window to the receiver and connect the receiver to the TV so you can get your satellite until you can get the cable fixed or replaced.

When I was bringing my SAT DISH and bedroom SAT RCVR with me from home I could never use the so called SAT CONNECTION on the outside of the trailer. It will not pass the DC Control voltage needed for the dish.

The way I got my setup to work was run two RG cables from the two port SAT DISH HEAD to two SAT RCVRs ANT INPUT connection inside the trailer. Then I ran VIDEO cable from each of the SAT RVCR to a VIDEO INPUT of the TV SET in the Living Room and the second video cable to the VIDEO INPUT of the TV SET in the bedroom.

Then I just select VID 1 on the trailer TV using the remote control unit.

I am assuming you must be at home and using your HOUSE SAT DISH to check things out with.

I routed my two RG cables into my trailer thru the storage bay door.

I would do this temporary to see how things work then decide how you really want to get setup with a portable tri-pod dish etc...

This is what worked for us for a season and when the NATL BROADCAST went digital we just stopped bringing out the SAT RCVR stuf.. Too much work to get the portable DISH pointed to the correct satellite for us...

I have no idea how the new SAT TV hookups are done today.

Digital High Def National Broadcast Channels TV from the local towns is great for us.

Generally that sat hookup on the outside is to feed the receiver inside, not the TV. Inside should be another coax feeding the TV or the switchbox from the sat receiver out

Thanks I will check the connections

It is also very common that manufacturers used the less expensive copper clad coax and this stuff does not work with newer satellite equipment.

If you're saying that your're getting a snowy picture when you connect the receiver (outside your RV) to the coax and connected the TV inside the RV to that same cable, then you definitely have a bad connection somewhere. The picture coming off the output of the receiver should be entirely free from "snow". Digital images such as those with satellite TV don't get "snowy"; they are either all there or they aren't there at all. The snow is coming from something in your system. Most likely one of the connectors on the coax is bad; that's pretty common.

That kind of problem with a coax will degrade the picture and add the snow you are observing. However, it will totally DESTROY the satellite signal if you try to send it down that same cable. That is why you can't get any signal if you move the receiver inside.
