The reason I am asking is because I am having problems pulling in strong signals that are only 13 miles away. Of course TiVo says it is my signal. But I have tried 3 different antenna and have purchased a cable coax tester to make sure all the lines are good. I have not had any success in trying to figure out why I am having issues and am very frustrated and tired of wasting my time and money. I was wondering if the tuner in the OTA only boxes were perhaps better at pulling in the antenna stations. I have the one that can do either cable or antenna. Thanks and appreciate any advice or tips. I am also running a distribution amplifier. My antenna is on the roof. I have tried dozens of combinations of different antennas and equipment and nothing seems to help. My older TiVOs pulled in the stations much better. A little flat panel antenna on one of my other TVs pulls things in better than the big antenna on the roof that goes to the TiVo Bolt. Love the DVR, but two of the stations are becoming unwatchable.
