I'd like to share this curiosity. Linked are traces showing axial response of a single array element. One measurement with each of the boxes two parallel NL4 connectors, and a known good box overlaid (in the deeper shade of salmon) as a reference trace. The reference box has a wider dispersion waveguide, hence the more ragged magnitude response.
Note the HF phase response departure on the suspect connector. When measuring the array we were absolutely certain we had a compression driver out of polarit . I now suspect a failed solder joint.

A new connector plate is inbound from the manufacturer, who has provided fantastic support this far, and would like the bad connector back for analysis.
