Satelite\Cable
I have 2 connection in back of my trailer satelite and cable. The satelite will work only on one TV while the the cable will work on all TV's any thought. I was told this is custom on all trailers.

On ours the sat connection only goes to the entertainment center where you can hook it to the back of our sat receiver and then form the receiver to back of the TV distribution box so it will go to all the TVs just like the cable.

This is because the cable line will run through a splitter and possibly the booster too, whereas the sat connection has to be a dedicated line.
When using sat, there is a voltage sent from your receiver back to the dish to make it operate and this circuit can not be interferred with.
Most trailers only have the cable connection on the outside and you have to do some modifications to make it work with a sat...ie. disconnect it from the booster/splitter.

Whatever you do - don't connect a sat reciever to your "OFF AIR" antenna. Wiengard blade antennas have a signal booster that is powered by a small amplifier on the back of the antenna connection wall plate. It has it's own power signal used for a signal booster (amplifier) and if it is on the same cable as a reciever, one of them won't be around very long...
Your satellite line has got to be seperate from the roof top blade antenna for this reason.
And like I mentioned above - some of those AV switch boxes will not pass the DC power signal for your dish. The way to test for it is to hook a reciever on the "OUT TO TV" side of the switch box, and see if twelve or eighteen volt makes it to the "FROM SATELLITE" connection farther along the box.
If it doesn't - your reciever must be before the switch unit. And YOU CAN ONLY HAVE ONE on that cable line.
The good news is that if you have two outputs from your dish - you can run another cable for the other side of the dish, and thus a second reciever box.

i know home-based satellite systems require the use a multi-switch to allow different reciever(s) to select the desired satellite transponder. (ie: so different reciovers can watch different channels...)
perhaps you simply need a multi-switch? they are not expensive.
or if you don't mind watching the same satellite channel on both tv's, simply split the output from your receiver...

The AV splitter box will send an output to "TV2", but you have to put the sat reciever BEFORE the AV switcher (dish side of it).
NOW - if you put a multi-switch on the dish side of the reciever, you can run a cable from there to another reciever.
Likewise you can use the second output from the dish itself to run another cable anywhere you want to. BUT!
You still have to run cables. Plan that carefully in a trailer or RV of any kind, because it won't be easy if it is from the living room entertainment center!
You also will have a switching problem at the back of the second TV.
It needs the signal from the TV2 line out of the entertainment center, OR from the second reciever. A simple A/B switch works perfectly for that.
