Subject: Re: [TowerTalk] yagi antennas breaking elements
I looked at the manual and the tips appear to be Ø1/2" tubing with .049
wall, I am not sure what grade. Perhaps upgrading to a .058 wall 6063-T8
aluminum tube would work better. Do you have end caps that may be trapping
water? Rope is also an option and probably a requirement for Hy-Gain beams.

hello
I have had a problem with my M2inc antenna, 15M6DX over the years.
I has 6 or 7 times different elements tips beaking, really is
unbelievable that this happen, and seems is worst now, actually I have 3
tips broken in the last weeks
I am in a windy location, maybe the vibration is causing this.
What will be a solution for that?
I heard about a rope inside the elements, but will add weight to it
Others are using expanding foam
What do you think about that?
thanks in advance!
