I am not an expert, just user. Depends on your location, type of antenna, and terrain between you and the station broadcasters.
I have several types of antennas. They all seem to work about the same. I buy the ones that have the longest range in miles. You position the antenna at a high point in the room near the TV, hook it up to your TV coax input, select the TV or antenna input on your TV menu, do a scan for channels. It will run through all the channels digital and analog and your done.
Sometimes the stations change, so you may need to rescan after a few months.
