Now, I’ve gone and done it. Turns out the little antenna that comes with my Hauppauge 950Q works better than any of the myriad of antennas I tried from Best Buy and Radio Shack. I ordered one for each TV.
They work so well in fact that I just hung up the phone from talking with Time-Warner Cable and having them disconnect my cable. Can I get by with my five broadcast channels and IPTV? Have I lost my mind? Kind of panicking here.
