Sorry For all the questions but I just got setup today and am now doing my own tweaking. I unplugged everything and used a channel master 4002 to diplex the signal I hooked up my HDDVR with AM21 with the 4001 and got everything working. Then I realized I dont have any more RG6 cable to diplex out my other two standard receivers. If I just plug in the original cable like normal it will have both SAT and OTA on it, is it still ok to plug into the receiver? Or should I make a trip to Wally world real quick?
