Thanks for the information. I guess I will see if STAB ever responds.
In the meantime, I decided to try to fix it myself. I had an ant colony living in it, and they ate the paper on the ribbon cable and corroded the F-connector that goes to the receiver. I spent some time last night and replaced the ribbon cable and connector, and it's back to working, at least on the bench.
Seal the seams up. Silicone caulk is perfect for this, as if you ever have to get back inside, you can peel it back off without too much work.
