This ring is called the Clark belt.<br />This Clark dude figured that this is the distance that sat's of similar mass will stay in a stationary orbit.<br />To cut a long story short...Imagine a arc, similar to a rainbow with its highest point due north. The elevation of this arc is 50.28 due north, here in Sydney, for example.<br />Now to "follow" the arc, the motek have off centred the arm by 30deg. so as it goes west or east of centre it actually tilts the whole dish.<br />so at 80 degrees west (280 deg) the dish is virtually laying on it's side with the arm of the LNB now horizontal. So it sort of twists, rather than turns.<br />I hope this clears it up a bit <img border="0" title="" alt="[Wink]" src="images/icons/default/wink.gif" />
