My cables from the satilite to the switch box (SW44) have to go about 100 feet because the south of my house is trees and i have a dish 500 mounted on the side my barn. it looks at 110 and 119 satilite. i have read that an amplifier could help raise signal strength by amplifieing the signal. on the switchbox it has satilite 1a,1b,2a,2b on right and power inventer, output2, output 3 on the right. they go to my 3 recivers. where should i put the amplifier like inbetween what?
