Here is how I had my DishNetwork setup in my RV. I used a DVR that supported two TV's.
- The dish (aka satellite antenna) had one cable going into the entertainment center to a signal separator (looks like a splitter, but separates the signal into 2 paths - a splitter will not pass thru the 18v from the receiver to power the LNBF).
- The separator had 2 outputs which connected to Antenna Input 1 and Input 2.
- TV1 output went into the main TV Satellite connection on my Winegard switch.
- TV2 output went into the bedroom TV Satellite connection on my Winegard switch.
Everything worked perfectly. When I upgraded my main TV to HD, I then removed the TV1 cable and ran an HDMI cable from the receiver to the TV HDMI in connection, bypassing the Winegard switch. I then switched the TV inputs using the INPUT button for the TV.
The receiver does get a bit warm. It is made to sit out in the open with good airflow around it. I found I had to leave one of my entertainment center doors open to let the heat out. I forget the exact temperature, but at a predefined temp, the receiver will shut down until it cools down.
