Does anyone have any tips for installing a small dish i.e dish or directv on a sailboat?? Of course it wouldnt be for when out at sea but when in docked in port at a slip, or maybe when anchored depending on sea conditions. I've heard of mounts on a servo motor which is controlled on signal strength but sounds pricey. Also, when in port will minimal wave variations affect the incoming signal to a degree where it will disrrupt the incoming picture?? Any help would be greatly appreciated. Thanks.
