Mounting a TV antenna with a bulldozer

November 17, 2009 by Alexandru Csete

My parents needed a new TV antenna for UHF because the old one was broken. So that’s what we did this nice and sunny Sunday. Unfortunately, we do not have a ladder that is long enough so we had to improvise with my dads bulldozer 🙂 Watch in high resolution

Do it yourself HF2V

February 13, 2019September 27, 2009 by Alexandru Csete

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!

First Impressions of the Arrow II Antenna

January 23, 2017August 11, 2009 by Alexandru Csete

I heard about the Arrow II Satellite antenna quite some time ago and even seen a lots of videos about it on YouTube. Unfortunately, whenever I look for an opportunity to get one, I couldn’t find it anywhere in Europe. Until recently, when I learned by a coincidence that Antenna Warehouse is also shipping them … Read more

HF2V on the Air

August 21, 2016May 4, 2007 by Alexandru Csete

As you can see on my HF2V pictures, my HF2V is mounted in between a lot of trees. There is even electric fence only 10 meters from it. Nevertheless, it performs very well both on the RX and TX side. It has also been standing for more than a year now and can cope well with the winds on the Danish west coast.

Tuning the Butternut HF2V

February 20, 2007 by Alexandru Csete

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.

First HF2V Measurements with the miniVNA

As I mentioned in my previous post, I have bought a miniVNA antenna analyser and I have now done the first meanurements on the HF2V.

Butternut HF2V for the 160-30 meter bands

August 21, 2016February 18, 2007 by Alexandru Csete

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.

I just can’t resist the HF2V

August 21, 2016February 12, 2007 by Alexandru Csete

The weather got milder today. It was foggy, very little wind and about 4C. I simply couldn’t resist making one more attempt on erecting the HF2V.

HF2V Assembly – But no Erection

August 23, 2016February 10, 2007 by Alexandru Csete

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.

DX-88 Overview

December 8, 2005 by Alexandru Csete

The DX-88 is a very good vertical antenna by Hy-Gain, which covers the 80, 40, 30, 20, 17, 15, 12 and 10 meter bands. With an optional kit the DX-88 can also work on 160 meters. The antenna is self supporting and comes with stainless steel hardware making it quite robust in windy conditions. Like any other vertical antenna, the DX-88 performs best with a ground radial system.
