If you want to get all of the local channels in this area, you'll definitely need an outside antenna. From your location, WCBI is the closest of the five stations and more easily received by an indoor antenna. WTVA, WLOV, and WKDH are in the same general direction, but are farther away. WMAB is even farther away near Ackerman and therefore is not in the same direction as the other four. So, to get all of them, you may need to consider a rotator depending upon what type of antenna you get. To complicate matters even further, WTVA and WMAB broadcast on "high VHF" channels, RF 8 and RF 10 respectively. These channels will absolutely be extremely difficult to recieve with an indoor antenna. (I'm in Starkville, much closer than you are to the towers, and can't get them with any indoor antenna I've tried.) These 2 channels are also more prone to interference during thunderstorms too.
So, there's your problems, what's a solution? Check out the web site "antennaweb.org". Plug in your address and see what it recommends for where you are. But I believe your best bet is an outdoor antenna.
