I've had a few occasions where, under very heavy seas, my VHF antenna has
whipped forward and managed to catch the anemometer cups and get jammed,
causing me to lose wind speed data. Looking a photos of the masthead it
appears that the antenna is made by Metz. I'm very limited on where it can
be mounted and was wondering if there were rigid antenna that wouldn't
whip?

an even better idea is to get rid of the moving plastic aloft
and go with an ultrasonic wind sensor which gets speed and
direction with *no* moving parts.
