I am using a dish 1000.2 to get 119, 110 and 129. For my hd locals I am using a left over 500 with a dp twin lnb for 77. Going by dishpointer I have the 500 elevation at 44, the azimuth at 174 and the skew at 80. It works, but the best signal strength i can get on transponder 4 is 31. My neighbor has a 1000.4 and he gets 51 on transponder 4. Any suggestions on how to tweak this better?
