There are NO differences between TV antennas and HDTV antennas! If you're using an antenna now, it will work just fine on HDTV 99% of the time... on even more channels! Most antennas shown on this page will receive both UHF and VHF HDTV signals.
What's NEW is that HDTV signals are much clearer. All you need is an antenna and a Good Converter Box for tuning old TV's. By law, HDTV tuners were built into ALL new sets from 2007 on.
