I would start with substituting the 9:1 balun for a known good one. Also try
substituting out the terminating resistors. Lightning could have got the
resistors?
I would also try your analyzer on the feedline using a dummyload at the
opposite end OF THE COAX. Check for an open or short in the coax.
If the wires are visibly OK, it can only be one of those three things.

Subject: [tdxs-list] Beverage Antenna Problem
I have been trying to repair my 4 beverage antennas. Wires and terminations
are good. 2 of the beverages work well, 2 are "dead" I have checked the coax
and connectors are ok. Other than broken wires, what can go wrong with the
transformer? What the heck am I missing? Short to the core? I will try
moving a transformer from a working Beverage to a dead one to see if that is
the problem. Both "dead" ones have RG-59 coax with foil and shield to them.
The working ones have other types of coax. All have transformers from ON4UN
that used to work great. 3 are 600' one is 800' the 800' and one 600' are not
working.
I guess I should try the substitution of another transformer first...
Thanks
Chuck W5PR
