I moved one of my receivers out of the house and to an outbuilding about 200'-250' away from the dish. I ran rg11 cable from the dish to the receiver. I get some channels fine but some channels say acquiring sat signal. When I check signal strength the strength is over 100 and it blinks between locked and wrong sat. I also put an inline boost at the dish. Can anyone give me any advice on how to fix my problem? Thanks.
