Seems to me that you've pointed the dish correctly, but not selected a clear hole through the trees. You're probably getting 110/119 through some minor obstructions and are blocked completely on 129.
Without a smartphone available, it's purely trial and error to find that open shot. You're close, so try moving up or down, left or right in small increments.
