My HR 20 died today so I hooked up my H23 in it's place until the replacement arrives. I hooked up my OTA directly to my TV and I was stunned at how many more channels I am able to pick up. The range increase is just remarkable. The channels that used to be shaky as far as signal is concerned are now coming in perfectly with zero pixilation. The PQ has never been better. What is it that my HR20 was doing to impede my OTA signal? Is this common? Is my OTA working better because the OTA coax is now connecting farther away from the DVR connections? Should I be insulating the coax on my OTA or something? Any ideas on how I can get this same reception for my replacement DVR would be greatly appreciated.
