Thanks for the report with the good news.

Good detective work, kach22i.

Near as I can figure it, the connection was cocked just a little too much (90 degree bend) and was shorting. Happenstance (the Devil's work) it went out while working on the other end when changing out the 5-foot pole for a 10-foot pole.
That sounds like "cold flow"" of the center conductor through the dielectric so that it made contact with the shield and caused a short. This happens when the coax is bent in a smaller radius than allowed by the specs, especially in coax that has a foam dielectric.

I enjoyed the photos, and was wondering how he combined the UHF and VHF sections, until I saw the shorting stubs.

Yes, you would think so; seems like a contradiction in terms.
