i have set up dpp twin pointing to 110 and 119 and an other single dish lnb pointing to 61.5 i am using sw21 heaving one input from 61.5 and one from Dish pro plus twing lnb (for 110 and 119), problem is that my receiver lost signal after few minutes, when i use only 61.5 it works fine or works well for only DPP twin, it lost signal whe i connect both LNB's. I tried to connect 61.5 directly to input port of Twin pro plus but its not getting signals, I reads lot of posts and just guess that may be my receiver(PanSat 3500SD) is not providing enough power to LNBs. can any one help me. what is problem and what could be solution? thank you
