Revision as of 18:37, 5 July 2007

I am trying to improve signal on a 800 mhz sytem that is around the 70 to 75 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 800mhz beams for some good prices on ebay right Here. Also be advised that the 1 to 2 bars is with the amp that I am mounting by the antenna, but I connected it down in the scanner shack tempararely until I put it up on the mast. Without this amp in the shack I barely get the control channel.

I was searching for an amplifier that was not alot of money but the performance to be good. 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 (Marda1100 Drop Amplifier) and will be 15 DB's of forward gain and a return path insertion loss of 0.5 DB's. I purchase mine from Ebay Here and 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 Company. There is two ways of powering this amplifier, one is Local powering and the other is Remote powering (requires power inserter)

Here is some infoon powering this amp. I am going to be trying the Remote Powering set-up and will eliminate one cable. Local powering you would be running two cables which would be RF output cable and another for power. It uses regular coax cable for power and connects to the adapter which has F female for you to connect. I will mount the power inserter in my shack under my desk where the coax cables come in. The coax I am using is about 75 feet long and is Times Microwave LMR400. More to come!
