Hi all. Got great deal from DTV for additional receivers, unfortunately received HR23 and H23 instead of new receivers. Oh well, these are for secondary rooms. My Question. Do I need Deca boxes for these recievers to connect them to my whole home setup. My current setup. SWIM DISH, Deca box connected to SWIM Splitter and my network, HR 24 and H24 units connected to SWIM Splitter via coax. I do have ethernet available at all my televisions. Thanks.
