When the signals come out of the LNBs they will be in the Ka-lo band which overlaps the OTA (UHF) bands, so you can't have DirecTV satellite signals and OTA on the same cable.
Each new DirecTV receiver and DVR comes with devices called "b-band converters". These take the Ka-lo signals and move them up to Ka-hi so the receiver can decode them. In theory (and we can't test it until the new sats start transmitting, probably in mid 2007) you could put the b-band converter at the output from the multiswitch, then use diplexing to put the OTA signal on the cable and remove it using another diplexer at the receiver like you do today with the 3-lnb dish and the satellite signals from101/110/119.
There will be no difference between the losses using a wide-band splitter and a narrow-band one, when used for narrow-band (OTA) signals. 3.5 db is what you get with every two-way splitter, unless it is VERY badly designed.
