[TowerTalk] Re: Antenna element vibration damping - How

[VE6JY Don Moman]

elements made from the .065 wall aluminum don't seem to exhibit this
tendency.  A little thicker than the normal .058 (the stuff that costs 4
times as much) and designing them to have a bit of droop - works for the
many OWA stlyle yagis here, none with ropes, and no/minimal vibration
either.
