Normally, if you have a correctly peaked dish (including a plum mast) then there should be no rain fade unless it is visually impairing or black clouded sky.
If you want to get a hacked setup going with the most signal possible, try three 1000.2's, each with "W" brackets. Place a DP Dual/Single LNB in the center slot and point each to the separate sat. If eastern, then 61.5, 72.7, 77. If western, 110, 119, 129. Then take the lines from each and run them into a DPP44 switch (or DP34 if single tuner or running dual lines). Set the skew on each to 90deg and run the elevations per each orbital location and then just horizontally peak each. Gains on each should get you in the 90-100 on each one. The issue with the 1000.2 or 1000.4 dish is trying to cram three orbitals into one LNB, you loose on one to get another. If separated, then each is going to be the strongest they can be. This is the way all commercial setups are done.
