I asked our municipal POC to source a list of protectors that pass the

We noted this is UL497E and not the UL452 (radio & television receiving
equipment) / UL 1449 (surge suppression) that was originally called out,
and were told this is the only option, and specifically "told not to
press the issue".
And, as noted, they won't work for your chosen antenna, for the reasons
noted. You should probably pursue one or more of the options for
antennas that are relatively well matched to coax on their operating
frequencies.
