Or are you saying the antenna would bow of it's own weight? That is a flimsy antenna. Yes. It was flimsy, but so is a reed, and those evolved to live with the wind. Watch the way grass moves. Those things don't even have guy ropes, my antenna mast did, so if anything it got an 'unfair' advantage... Obviously this method won't work for a heavy antenna, but something with little weight, little displacement off its vertical axis, and little wind resistance compared to its mast, will work. Just pick a material that is never bent beyond its fatigue point. Like I said, FIFTEEN YEARS. Storm force winds too. If I hadn't seen it and done it, I wouldn't be saying it. I can add a small remembered detail about the point where I added the guy lines. When I first placed the mast vertical, just to see it that way, I noticed one major node that tended to stay still, roughly two-thirds up it. I decided that if I guyed the mast not exactly at that point, but slightly offset from it, it should damp resonaces in a similar way to the placement used to damp a guitar string. That way I get the best placement, combined with enough damping to prevent the oscillations building up to a critical level. It worked. My neighbours became convinced at around year five, but I managed to calm their anxieties beforehand. ![]() |
