The arm of the 1000.2 is put on with rivets, the 1000.4 arm bolts on from the bottom. He is having to do some "jerry rigging" if he is doing that. Are you using a DPH LNBF on that 1000.4?I *think* he is just swapping the arms out & mounting the hybrid LNB. That way, he doesn't have to realign much, if any. I can tell you that my signal strength on the 02 dish is 3 to 4 points lower across the board than while on the 04. Either it's just not as finely tuned or, the smaller dish has a bit of drop-off.
