I know its not enabled yet but wanted to explore options for hooking this up. First any danger in hooking it up before the HR20 is capable of handling the input? Second would you use diplexors or just run a seperate line for OTA? My guess is seperate line since in future diplexors wont support some of the new sat capabilities? What type of cabling should I use to carry the OTA signal to the receiver? Should I ground the OTA outside as well as going through surge protectors inside?
