More likely that the tree is a problem. 50 feet is a pretty short run. I have used 59 several times when it was already wired and it works fine. One thing to check is to make sure that you are getting the right satellite on the right eye of the LNBF. Cover the 110 eye and make sure that you aren't getting 119 on that instead. Then peak on that eye and run a check switch. You should be good to go (assuming you have your skew and elevation set right).
