When I was a tech, I made extensive use of the 1000.2 WA because it was much easier to set up, more versatile in configuring receiver setups and most importantly, the 1000.2 displayed better signal strengths.It has something to do with the fact that the EA dish, like most multi-slot pizza dishes, isn't perfectly parabolic and when combined with the WA LNB assembly, there are some serious performance problems. My local dealer has a bunch of 1000.4WA dishes and DISH won't let him use them.
