> An antenna that needs ropes in elements are poorly
I disagree with that. My Rohn 25G with open ends at the top (I use
it as a vertical antenna and for supporting ropes, no yagi's) vibrates.
I'm not worried about the vibration because it is steel. I did know of
a fellow with an aluminum tower who lost the whole top 30 feet or
so of the tower in a mild breeze, because it vibrated and cracked.
As I look back, most of my tubing antennas vibrated. Some of
them had end caps and vibrated, but rope always fixed it. I had that
problem with Wilson yagis, and everything else.
I don't think that means the antenna is a poor design...not when it
is a problem so easily cured.
