It works like this: one line in from your stacked lnb to the 2-way hi-freq (up to 2150 mhz) splitter. One leg goes into the Sonora destacker, and from the destacker it goes into the 18v side of the 3x4. The other leg goes straight into the 13v leg of the switch. Then take two leads out to your tivo.
This is a complicated, expensive way, but it works. The stacked lnbs run about $119.00, and the destackers cost about $79.00.
If you also use standard DTV receivers, go into the LNB setup menu in the receiver and set them up for stacked lnb's.
