I am in a heavily forested campground, and using the 25' to 50' cable I cannot find an open space to "see" the right satellites. However with a run of about 400' I can get to an open area with a good view of the satellites, but the x2 just does not seem to be able to function it "wherrs" and moves somewhat but never seems to be able to lock on to the satellites. I have used this same x2 in areas where it has a clear view and is within 25-50 ' and it works fine. Comments and recommendations Please?
