in the digital world that is one channel, probably a PBS station. Google to see where the closest channel 33 is to you. if it is not the larger city near you rotate the antenna and try again, here I have 6 channels with each having 2-5 sub-channels. if you are in a rural area or are far form a major area that may be all you can get at home. the selection will very everywhere and you need to re-scan at each location as even if another location has a channel 33 it is probably not on the same frequency.
