Over the holidays, this sensor went flat.  Investigation found guy line rope had parted where it turns through the ground anchor eye.  One cup was broken and the rotating shaft looks to be bent now too; I'd say it isn't likely repairable.  Photos attached.

On Tuesday, I'll replace it with my last unit available and also move it.  Additionally, I'll add chafe protection to all the guy lines.  Guys will be wire when they get to a permanent location.
