Butternut HF2V check 2011

HF2V full shortwave scan 2011.11.26I 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.

The Butternut HF2V antenna after three years

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.

Lucky DX, again…

I don’t know how it happens, but very often I find myselv being on the right frequency at the right time. The right time means when a DX station starts calling but before the crowd begins shouting.

Tuning the Butternut HF2V

Like with any other multi-band vertical the different bands are coupled with each other. This means that modifying the settings on one band will influence the others. This effect is worst on the low bands (40 and below) and less noticeable on the higher bands. If you only have the basic two-band HF2V there are only two bands/parameters to adjust and you can easily get through the alignment by doing a few iterations on each band. However, if you have the 30 or the 160 (or both) extensions mounted, aligning all 3 or 4 bands can become an endless process.
