Wouldn't wouldn't water in the coax cause fluctuating SWR and poor antenna 
performance?  Have you tried QRO?

      Yep. The antenna acts like an antenna and functions normally.

      What hairpin match? SteppIRs have an internal balun.

  doubt it's from your splice, if done properly.
      The only way to check a balun is to substitute another one. In the case 
of the SteppIR, that's not possible. 

      I think what the problem is is water ingress to the dangling damaged 
coax.
