A:Answer Antennas are not really tied to TV models. All you need is an ATSC HD antenna.
All new digital TV's sold in the US support ATSC (the digital TV transmission format).
You might want to try something like Mohu leaf, or any of the several HD antennas available in store, and see which ones work best for you. At the end, results will vary depending on your location from TV tower and the quality of antenna, not the TV.
