Received the 9241 package with the two lnbfs and the s 44 switch. also got the winguard 30 inch offset oval dish. I have an exsisting 1000.4 dishtv on the roof. first im wondering if i could use the 1000.4 dish to get 91 anik 1 if i switch to a singal lnbf? and just use the 30 inch for the anik4 at 82? also does the s44 switch have to use the power supply or can use the exsisting switch that dish has on the roof already? Another question when dishtv installed the line running to my main tv. the combined the two cable into one coming into the living room before entering the house and they are split i into two again once inside the living room. since i have dish 612 im guessing i can just connect all the exsisting cables as is to the 9241?? sorry for so many questions im kind of new to self installation details. thanks paul
