radio aerial (antenna) won't stay in position

It now refuses to maintain its position at an *angle*. Slowly but surely it drops down until it reaches the horizontal position. The small screw has been tightened up, but even as tight as we think we can do it without stripping the slots in the screw head, it is not enough to *clamp* the aerial to stop it dropping down. Basically the aerial at its base is a square shape with one small bronze coloured washer each side of it and that all sits in a ' U ' shaped base with it all being clamped with a small screw. Are there any tricks you know of, to get it to behave? Thanks. Cyanoacrylate Geez. It`s just gone a bit floppy, the spring washers have lost their tension, it shouldn`t be beyond the wit of man to either retension them, find an old aerial from which the springs can be salvaged or if it comes to it, purchase a replacement aerial from which the springs can either be used or if he`s lucky enough to find a good match, the whole twig can be used. Here in the UK several companies spring immediately to mind who stock quite a good range of generic replacement aerials, a bit of fiddling will probably result in a workable solution. Ron I agree Ron. I've never seen so much nonsense spouted about what is fundamentally a simple problem, which those of us in the trade see all the time, and have posted back here how to fix with a minimum of fuss and tools - certainly not including drills ... !
