How come there is such a high current drain to drive the switch plus the 
LNBs? From what I understand, the switch should only power one LNB at a 
time. Usually the switch plus the LNB should not drain more than 
300-400mA, or am I wrong here?

I think this could be done. Nevertheless, the card would still operate 
outside its specification.
