Several years ago I made the mistake of replacing my 04 KVH sat dish with a in motion King Dome. What a POS from King not honoring their own warranty in the first 6 month (yes I sent in the warranty paper work). When the in motion worked (about half the time) it had trouble staying locked. Currently it locks on the wrong sat and will not continue to search. King support could not solve the problem over the phone and suggested I replace several parts (total cost of $450) and I'm pretty sure I've been banned when I asked why I'd waste $450 on their POS when I could buy a Tailgater for about the same amount of money.
OP, my point is if you cannot get it to work fairly easily, do not waste any money on a dish that old as there has been many good improvements in design.
