I have a full sized M2 40M3 yagi at 120ft.  It's been up about 5 years.  The
distal element taper is aggressive, ending with a 3/8 inch diameter tip on
each of the six elements. Too small in hindsight!

The 3/8 inch element tips are failing (it appears from a vibrational
mechanism).  It's disconcerting tofind a 20 to 30cm section of aluminum with
the mower blade :-)

Q1). Has anyone else had this problem with the M2?

Q2). Has anyone else modeled and/or implemented a less aggressive taper
ending at 1/2 inch distal tips?

Thanks in advance...

73, Scott W3TX
