Buy a good and "real" preamp - UHF + VHF - the kind with one piece that installs on your antenna and a box that plugs into AC inside your home. Not only will it help you pick up the south Buffalo channels it will boost your signal strength across the board. Some people may say there's no difference in picture qualify or reception if you have 20% vs 90% signal strength, and they are correct, but just wait until days when the weather is poor or winter for that matter which typically (for some reason) lowers the signal for quite a few south channels.
