Had a similar thing on a tower in Cyprus a few years back. Swapped cable twice, used shielded cable, tried all sorts. In the end we put the original cable back (none shielded, nothing special outdoor cat5e) but put ferrite beads on the cable and no further issues ;) Have put ferrites in every AP ever since and surprisingly never seen this issue again.
