Network (free) stations not all available

Coverage is spotty and I am not able to view basic, network stations. I have moved the antenna around several times to get a clear picture, but it does not work. In my area, of 6 stations, I get 3 clearly during the day, and 2 in the evening. May purchase a stronger reach than 35 such as 50 or 100 miles, or another product altogether. Not happy with this purchase.
