Advertisements Hello. I am in the process of splitting my OTA signal from my outside antenna to 2 seperate HR10-250's. I'm sure you've heard this but i'm tired of searching so here it goes. When splitting the OTA signal do i need one diplexor or 2? Right now i have one diplexor at the first HR10-250 but not at the other and i'm only recieving 3 channel's at the other box. The first box i'm recieving 8 channel's. Should i be purchasing another diplexor for the box recieving only 3 channel's? Any help would be appreciated.
