Antenna mounted Amplifier Project

I am trying to improve signal on a 800 mhz sytem that is around the 60 to 70 km range. Currently I receive this system at around 1 to 2 bars on my BCT-15 using a 800mhz Wilson beam. You can find these beams for some good prices on ebay right Here So I started searching for an amplifier that was not alot of money but the performance to be good. So I source out a company called Electroline. They make all sorts of drop amps and accessories. The amplifier is made by Electroline for Marathon Industries. I purchase mine from Ebay Here Here is a Picture of the amp I Purchased. If you notice in the picture I provided, there is a power inserter that I purchased separately from this [http://www.homenetworksupply.com/default.asp Company. There is two ways of powering this amplifier. One is Local powering and the other is Remote powering (requires power inserter)
