My exact problem too!
In my case, the long mobile 2m monoband whip they offer. One day it simply died. All the componentry is sealed in-so no repair possible.
Similarly, poor performance with friend's Diamond base antennas. Either blows up or dies from water ingress.
Comet is sweet. I highly recoomend the GP-3. One piece construction and the beam isn't so flat like the GP-9. I think the GP-3 comboned with a 50 watt Yaesu mobile is the perfect combo that should last forever. Make sure to use black goop seal on the outdoor connector. You will be all set for the long run!

Avoid Diamond!
Interesting. Can you elaborate?

I bought a diamond X510HDM dual-band vertical, their version of the Comet GP-9, specifically because they claim it could handle 330 W FM on 2 meters, an 250 W FM on 70 CM. I wasn’t going to run quite that much, and quite a bit less power than that immediately fried the little capacitors in the antenna.
To say I was annoyed is an understatement.

A friend took the antenna apart and replaced the caps with larger ones, and I have had no problems since. But still, I would be wary of their power-handling specifications.
