More than three years ago that I have mounted my Butternut HF2V multi-band vertical antenna outside and left it suffer from the windy and humid Danish climate. The settings and performance that I could achieve back then are documented in several blog posts, e.g.Tuning the Butternut HF2V.
What has happened with the Butternut HF2V since then? Well, nothing really... During these three years, the antenna has been standing and performing very well without any need for fixing or tuning it. I have done a visual inspection and tightened the guy ropes every now and then, but that's all. In order to document it I have taken a few photos and made some SWR scans.
