Interesting Bill. Not sure why you had that experience.
At my qth, I double hoseclamped every place on each element that previously
used one hoseclamp.
I then used a pair of "dykes" to cut off the ends of the hoseclamp and taped
over them with Scotch 88 to prevent them from snagging on guy wires and
other things. I also double nutted every place where there was one nut.
Maybe this would have further reduced any vibration taking place as your
element tips were working loose? Possibly you also have a constant steady
breeze at your qth? I imagine that that could be a big factor as well.
Although I get heavy wind pretty often (especially in the Spring, Fall and
Winter) there are also long periods of calm at my QTH, as opposed to say
Long Island where there is almost always a wind.
I have no doubt that there is still element vibration taking place in my
elements - I just tried to take precautions to reduce it as much as
