has anyone been using the ota antenna instead of the cablecard from the cable company. how is the quality. does one antenna work to replace both cards allowing the dual tuner to work. also, i have two tivos, so can one antenna work the 2 dual tuner tivos? can anyone recommend a good INDOOR antenna? Last question... if i use an outdoor antenna, can i attach it to my cable coming in to my house from the cable company via a splitter and have it work will all my tvs. Note: i am not stealing cable in case you were wondering as it in included with my monthly development fees so even if i cancel my hd service, i still get standard cable.
