Since our ancestors walked upright and learned to use tools, we humans have longed to be warm and dry, well fed, and, no doubt, entertained. In todays world, entertainment is one way that we relieve our tension, and our hunger for it is the reason we see at least one TV on nearly every new boat over 40 feet. Were accustomed to getting our favorite weekly shows and sports specials offered by dockside cable hookups and satellite systems, but enjoying these diversions while we relax in the natural pleasures of remote locations, in our favorite spot on the boat is quite another. The answer to our entertainment needs has come in the form of small, lightweight, and relatively inexpensive satellite television receivers. We're talking about stabilized tracking antennas, which react to motion so quickly and through such a large degree of tilt and swivel that we can watch TV while the boat is underway, at speed, in normal sea states.
