Have you gone through a buyers' guide yet? Several variables that might apply to you and not others. http://www.hdtvantennalabs.com/index.php
All transmissions are now digital but as long as you have a digital tuner (built into all newer sets) the good old days of rabbit ears work.
Winegards have always been good antennas but will also depend on how close you are to the signal. If you haven't looked check this site for digital stations close to you http://www.hdtvantennalabs.com/location/
