My CX-333 has been up more than 25 years, with absolutely no problems whatsoever. No moisture problems at the coupling - I check every five years. And, ?of course, ?using 9913 cable. It is a phenomenal tri-band performer for California, where we all live in Valleys, looking at our hilltop repeaters. I run 15 W - maybe 20 W - and I hit everything I need to hit.
