I've used two G6-440s over a combined period of 35 years. One was mounted
upside down at 5200 ft. & failed after ~15 years after a storm. It may not
have been properly modified for the inverted installation. The other spent
~20 years at the top of a 90' pine tree at 5900 ft. The tree recently died
& was cut down; the antenna was working fine up to the last day.
The G6 isn't quite as rugged as a commercial fiberglass-enclosed antenna,
but given it's short length I don't think it's much of a concern. If
severe weather is an issue, the exposed dipole designs like the DB-408 or
DB-420 are probably best.
