Yes, it works. You also need a dealer control pad (available for rent from KD as well) to make the change from DTV to Dish. You then must also manually change satellites if the channel you want to watch is on a different satellite which can be a pain. However, depending upon the age of your dome it might not work with Dish. Check the dome model number and serial number and check with King Controls (King Dome) to see if your antenna will work.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?
