I am new to this FTA stuff so any assistance appreciated. I am looking to get 2 culesat 4000 Pro FTAs (I like the channel guide) and get 110 and 119 on them. Since I had a dish500 twin lnb (internal SW21) this fed my 2 ecoshtar 2800s. It is my understanding that I cannot use the twin lnb anymore due to the internal SW21 not being compatible with the FTAs, so would I get 2 dual lnb (dish500 legacy? or dishpro?) does it matter?....pointed at 110 and 119, then 1 feed from each goes into 2 seperate desque? switchs and then each switch into each FTA box?....I have read that if you connect up the wrong lnb you can blow the input on the receiver...Also what sw44 or expansion switch options are there if 3 FTA boxes were used....
