Assistance with TV Antenna - No more Satellite

So after buying a Roku 3 and Chromecast, I have decided to cancel my DirectTV and save some money. But I still need access to my basic channels, like the news etc. ABC, NBC, Fox all those. I have heard people say they have bought antennas to achieve being able to still get their local channels.

Does anyone have any recommendations on a good antenna? (possibly one that the use currently)

Thanks
Kevin
