This LNB for the DirecTV Slimline (AU9S) dish replaces the standard DirecTV Slimline LNB to add SWiM (single wire multi-switch) capabilities which can provide DirecTV programming from all current and future Ka Ku Satellites via a single RG-6 coaxial cable run to a power passing splitter.  Then only one line is required from the splitter to each receiver, making it easy to upgrade from a single tuner to a dual tuner DVR and so on.  The SWiM products are a great solution to pre-wired homes.  This LNB typically receives signal from 101, 110, and 119 satellites when used with the DirecTV Slimline Satellite Antenna System.
