All TVs including new ATSC Digital ones use the same frequencies as older NTSC Analog sets. An amplified antenna is recommended because there is a threshold where a weak analog signal will be visible (with considerable static) but a digital tuner will not have sufficient strength to display a digital (no noise or static) picture. Outdoor roof Antennas work great as well, you don't need an HDTV antenna, discount stores should have one for around $30.
