In that case, would you like to explain the long list of failures on the 100mph rated Magnum 340 that I've shown, most with high resolution pictures, at http://www.gi0nwg.freeserve.co.uk/F12/index.htm This antenna was installed at a location which semi-regularly sees gusts in the 80mph region but only on the very odd occasion (once every few years) sees them get anywhere near 100mph. In fact, the local government owned weather monitoring station shows the maximum gust for a 30 year period in this area to be 87 knots (100mph). I think you'd agree that the 100mph version was probably the one to install here. We done our homework and that is why the 100mph rated antenna was bought instead of the 80mph one, but it still failed numerous times and in lots of places that the wind has no real effect on. I've taken a lot of stick from some people on this reflector for highlighting problem areas on some F12 antennas and have been called a F12 basher. Those people are very quick to come back on my comments and virtually call me a liar. To those people, take a look at the photos and then ask yourself what you'd say and do if you owned this antenna. Remember, it's supposed to be rated at 100mph and the local government owned weather station has only recorded a peak wind gust at 100mph in a 30 year period.
