I have an Ethernet cable running though my house, can I use a DECA Coax to Ethernet adapter to take my Direct TV signal from the satellite to a the to Ethernet adapter then back from Ethernet to COAX and to the Box?
The main reason for a no is because the conversion with transformers will not pass the DC voltage to the dish or LNB. Otherwise the loss in Ethernet cable is more than in coax so the cable distance would be less if you could get around the DC continuity problem.
