there is no such thing as an HDTV antenna. a 50-yr old TV antenna in good physical condition with the proper cable will receive the new digital signals perfectly well. lots of snake oil out there. an indoor amplified antenna may be adequte in urban areas but the farther out you get from the transmit site the less effective that antenna may be.
