I would recomend our Clearstream 2-V antenna. You will need an antenna that picks up both UHF and VHF. I don't have an exact channel count. However all the major networks are available and many other channels. ABC, CBS, NBC, FOX, CW, ION, etc.
Any object or obstruction can interfere with reception. You can move the antenna to try and give it a clearer view to the broadcast towers for better reception. Thanks.
