Reflectorees, Surprise surprise, yet another story of rivets failing on Force12 antennas. I've included a couple of quotes from Tom N6BT from July last year which make interesting reading. It looks like this isn't as rare a situation as Tom claims (I have only seen three F12 antennas close up that have been installed for more than a year and ALL have had the rivet problem). These comments from Tom are regarding a Magnum 340 which is installed at GI0KOW, which is unusable YET AGAIN due to YET MORE failures (and the factory appear to have completely forgotten what customer support is regarding this antenna). Maybe it's time Tom started to collate the growing list of problem antennas and figure out what is really happening instead of giving the 'I haven't heard of that before' response..... Caveat emptor.... 'Your experiences with all the rivets failing and the antenna "falling apart" is so bizarre that it is hard to believe.' 'Since the occasion of element rivets coming loose is such a rare situation, there is almost no data to ascertain the reason.'
