I have a Slimline5 dish with a four cable LNB with two HD receivers (H21-200 and H24-700) and I want to add a third receiver. Simple enough except that when the dish was installed we had to put it on the garage and I buried conduit with two coax cables and am unabe to get another cable thru the conduit so I am looking at switching to the SWM lnb, power inserter and splitter. So far I removed power from everything changed the lnb, ran the cable from the dish to the power inserter then to the input side of the switch then from the #1 output to one receiver, removed the b band converter, powered up the power inserter and the receiver. Changed the dish type from slimline5 to slimline5(swm). I have signal strenghts in the 90's on sat 101 and 119 but the reciever says message 771 can't find satelite. Not sure where to go from here, any guidance would be helpful.
