Our Windsport has the King antenna and it seems to work well. Somewhere in your coach there is a coax outlet that has an antenna booster built in. The booster is a little button for on/off and a small green indicator light. On our coach the outlet is up in a cabinet with the button on the backside and hard to see and get to, real PIA!!! If you have a box to hook up a DVD to the outlet should be right by it.
I've tried turning the antenna for better reception but doesn't seem to make much difference, maybe a little. I leave the antenna pointed forward and don't even mess with it now.
