I'll take some photos of some leftover scraps from my spectacular ice
failure last January.  I had one antenna on which all the elements of a
204BA were heliarc'd back in 1983 (at W6AQ).  This antenna lasted great for
years and years.  When I put it up at N5OT 18 years later and it got the
ice, it failed mostly at the welded joints.

In winds it was never a problem.

Mark, N5OT

MX to everyone who observes it.
