start easy with a simple portable KingTailgater or DishPlaymaker type automatic antenna with DISH... it is powered thru the coax cable, so no other power is needed. The receiver can be placed anywhere in your coach, or at the outside tv, and HDMI cable connects it to your TV if you want to view the HD channels(yes!). A simple coax cable is all you need from the portable antenna to the receiver, simple.
You can place portable antennas anywhere you like, or need to, to best 'see' the 3 satellites(southwest/west in the sky). You can even temporarily mount it on your rear roof, in easy reach of the ladder.
