It turns out I have some tree issues at 103w. My other dish started having problems in the same spot a couple of years ago before I took it down due to the mount rotting away. So I spent some time the other night and got a solid lock on 89W. The dish has very good reception considering the damage. I'll probably move it early next week weather permitting and try to get 103w again. Experimenting with a cheap WSI lnb I have and the Norsat shows roughly a 20% difference in signal. The WSI is the higher one.
