This twin output LNBF is used to receive C-band on two or more satellite receivers.  The BSC422 C-band LNBF out performs separate LNB and feedhorn combinations by eliminating the bends and reflections caused by LNB / feedhorn technology. The BSC421 provides a straight shoot from the dish to the active probe inside our “in-line” wave guide. This
eliminates loss and induced noise.

This is your best choice to receive C-band on a 1.2 meter or smaller dish using a conical scalar ring.
