I have tried to adjust the 30m coil on the HF2V in order to bring the resonance closer to 10.1 MHz. Increasing the length of the coild 17->20 cm did indeed move the cenntre frequency to 9.2 MHz, but going up to 25 cm did not seem to make a big difference; it only moved fc by about 250 kHz.

Butternut HF2V for the 160-30 meter bands
After my DX-88 died in a winter storm, I have decided to give the Butternut HF2V a try. This antenna is a 10 meter long vertical for 80 and 40, with extensions available for the 160 and 30 meter bands. I was rather curious about it since this is the only vertical antenna that provides the four lower bands in one package. Moreover, having used the HF6V previously, I had quite high expectations to this one. Although rather expensive, my success with antenna have been very satisfactory so far. As a bonus it even works well on 15 meter band with flat 1.2 SWR between 20-22 MHz.
HF2V Assembly – But no Erection
I have now received all the parts for the HF2V with 160m and 30m extensions, and I took a few days off in order to erect it during a long weekend.
Go for the HF2V!
We entered december, and the Christmas holidays are coming closer and closer. I had to make up my mind about which antenna to buy for my top-band adventures. As I wrote in a previous article I had some serious worries about the GAP Voyager DX. I simply can not afford to spend 650 euros on a vertical that may be destroyed by the first comning storm. The GPM-1500 was pretty much ruled out as well, due to low expectations on efficiency.
How about some top-band adventures?
Now that my DX-88 has died again (base element broken) I have been looking for new antenna possibilities. One thought that keeps bugging me is that I have never ever had a QSO on the 160 meter band. Since the days are very short during the Danish winters and sunspot numbers are something you can only dream of these years, I have decided to devote this winter to top-band activities.
