With a NM of 9 db I think that the low band noise would doom the project. Even if it didn't, your amplifier gain would need to be about 75 db. That would mean that the antennas would need to be about 1600 ft apart and spaced horizontally so that they don't aim at each other in order to work properly. From that location, 1600' of cable would almost reach your house.

I have actually built a beambender and know the process very well. You can see it here: http://www.bing.com/maps/?v=2&cp=r2q...q=hancock%20ma (rotate the image left for a better view)

It has a 4' dish aimed at Pittsfield, an 8' dish aimed toward Altamont, and 50 db of gain. It's mounted on a 60' tower and powered by a solar panel and two 12 volt deep cycle batteries. It works on 2 GHz.
