Two recordings I made during the 2011 CQ WW CW contest showing how well the Butternut HF2V receives on the 21 and 28 MHz bands. The videos were recorded using the Funcube Dongle equipped with the HF converter kit and my GNU Radio based software defined radio receiver, GQRX.

I usually check my Butternut HF2V vertical antenna every spring to see how much it has suffered during the winter. The winters in Denmark can be very windy and wet, which is not very good for an antenna. This spring I was rather busy and I postponed the annual check until now. I haven't used the antenna for a long time, so I didn't know what to expect. Physically, the antenna is still standing and only one of the four guy ropes needed to be repaired since the last check more than 1.5 year ago.

I took a few photos of my Butternut HF2V vertical antenna during my winter holidays 2010/2011. You can click on the images to get higher resolution photos. Enjoy!

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.

Often I receive emails from people asking for the dimensions of the HF2V elements because they want to build one themselves. Well, here are the dimensions for all the coils and capacitors. Good luck with your experiments!
