Satellite reception...... Help !!

Since you have found that the satellite needs a direct connection, you cannot run the coax through the "distribution box" or whatever it's called that lets you push a button to switch between cable, rooftop, etc. You need to take the distribution box out of the picture.

What I did was unplug the "satellite in" and "tv out" coax lines from the distribution box and connect the "satellite in" to my Dish network receiver. For receiver output, I used one of the red-white-yellow inputs to the television.

The external coax connection most likely goes thru your antenna amplifier/switch box. You need to have a direct connection to the receiver, not going thru the amp/switch box.
I only had a single external coax on mine. But that coax came into a coax wall plate with two coax connectors and a short coax cable jumpering the two together. The jumper routed the signal from the outside connection to the amp/switch box. I had to remove the jumper and connect a coax cable from the wall plate to the receiver, effectively bypassing the amp/switch box. And it worked fine.
But I would have to put the jumper back in place if I wanted to use park cable. So I added a second external coax connected to a new and separate wall plate specifically for the sat connection.
Look to see if you have a dual coax wall plate with a jumper across the two somewhere near the receiver. If so remove the short jumper coax and connect another coax cable from the wall plate to the receiver. If it does not work with the first connection, try the second one.

Some units have both a Cable and Satellite coax connector on the outside of their units, look to make sure there isn't a Satellite coax connector in a different location.

X2. Also make sure the amplifier for the crank up antenna is shut off. Nothing wrong with running the coax direct to the receiver, but it makes a cleaner install if you can use the normal input on your rig. Any modifications you make to the pre-installed cabling in your rig will most likely affect your setup when hooked up to CableTV or try to use your crank up antenna for over-the-air signals. It's a pain if you have to reconfigure the rig everytime you change your TV connection.

Sounds like the connection between the outside connection and the one inside is messed up. These tend to be mislabeled a lot of times. make sure that the cable you are connected to inside is actually the one connected to the ourside port marked Satellite.

I did a slight modification to the cable/antenna outlet inside the trailer so that I could use my satellite without running a new line. Now I can use the antenna or cable or satellite. I had to read through it a couple of times, but I'm pretty sure this was the link to the mod. that I used. Hope this'll help you.

Suggest you add your rig to signature so those having same or similar make and model can chime in.
Cable connection could be going through the antenna power supply. Satellite connections must go straight from sat dish to receiver.
You may check your documents to see if the rig came with a sat connection on exterior.

If you only have a cable hookup on the outside of the trailer,"afraid of bears'" link above will be the easiest way to go.

I added a separate satellite connection to the 5er. You can get a connector that requires a single hole through the wall that connects the dish directly to the receiver. no dealing with antennas and amplifiers. I use antenna connection to get over the air HD signals that I connect to the antenna input on the dish receiver so I can record over the air HD signals in addition to the signals from the dish. I am an HD snob and want only to get HD reception.

I have a satellite jack and a cable jack on my Sundance. My first attempt at hooking up my satellite was frustrating, that was until I plugged into the cable Jack! It seems they put the stickers designating the input cable and they got them switched at the factory. I just plug into the cable jack which is actually the satellite jack. Problem solved!
