I *am* a satellite engineer. I've installed and operated antennas from 1.2m to 9.3m in diameter, from Baghdad to London. I've never seen lighting strikes an antenna in person, and I've only ever seen a handful of documented cases. I've seen more of them destroyed by bombs than by lightning. We typically earth antennas, but only the most expensive installations pay for full lighting protection (which is far more complicated than mere earthing). Your external CAT-5 is fine.
