Matt, I made a Phase III conversion per your excellent instructions and it works quite well. Thank you for posting that.
"Due to software changes with DirecTV HD receivers if a slimline 5 LNB is used with the receiver set to slimline 3 an error code results,Here is updated information on how to make the small HD dish."
I have left our H20-600 set at a 3 LNB slimline ever since I made the Phase III conversion, but there has been no error of any sort. Maybe this software change does not apply to the H20-600?
