Sorry if this is a current duplicate. I have searched for an answer but can't quite find exactly what I'm looking for. I have a SWM-8 and Multi Room Viewing 3 HR24s. I have one location that I would like to have the capability to not only use the HR24 but I would also at times like to see the OTA signal from my Attic Antenna. The Attic Antenna isn't close to the SWiM-8. Can I use a Directv Diplexer at a convenient location to combine the Sat Signal for my HR24 with the Attic Antenna and then use the Directv Diplexer again to separate the signals, one for the HR24 and one for the regular Antenna input on my HDTV. Thanks for any help you can give me!!
