If this is a hobby interest, you may consider stacking or ganging two or four identical antennas.
http://forum.tvfool.com/showthread.php?t=1024 This strategy provides additional gain and directivity, theoretically eliminating the need for amplification. Ganging two or four 91-XG's would be a possibility if you were inclined to try.
ADTech and I agree that an amplifier in you location would likely be overloaded by the strong local stations.
FWIW a Yagi style antenna cut for channel 10, with sufficient gain (13dB or more) would be at least 18 feet long.
Again, this would be a hobbyist DX'rs project.
