Rick, I use the Winegard FoldDown dish aboard my boat while at the
dock. It is similar to the carry out version. Aiming of these types of
satellite dishes is completely manual. You must adjust the dish for azimuth and elevation after leveling the dish. If the boat moves sufficiently, you will loose the satellite signal making the dish useless while swinging at
anchor. Works great at a
dock though once the dish is manually aimed.
