Hi,
I have a motorhome with a single LNB crank-up dish. Unfortunately, the dish doesn't seem to work any more. Do the LNB's "go bad" on these things? Is there a way to test it? I had a crimp in the coax & replaced it, but I'm not convinced that it works correctly.

If I try really, really hard, I can get a signal strength of 45-50, but it seems to "flash" between 45 and 0, and of course won't lock on. I'm wondering if I accidentally did something to the LNB when I was working on the wire.
Even if this is something beyond my level, is this something an installer can check?


ps (sorry I posted this here - I didn't see another place for it)
