Down goes the MA5B . . . up goes the Hexbeam!

Yesterday, after a long time thinking about it, I finally decided to take down the MA5B minibeam in favour of a second hand hexbeam. Although the MA5B has served me very well, being my first beam and being a big improvement over the Butternut vertical in many cases, the gain figures for the hexbeam are better and those who have them swear by them.

The Hex Team! Thos EI2JD, Pat EI2HX, Anthony EI2KC
and Tony EI4DIB. What a crew!

So it was with mixed feelings that I finally decided to swap them. My antenna team swung into action here on Tuesday and consisted of Thos EI2JD, Pat EI2HX and Tony EI4DIB, without whose help it would never have happened.

I already had the arms and the stay ropes of the hexbeam assembled to move things on a little bit. Working in a very confined space with the hex was difficult, but we worked well as a team, ironing out the problems as we went along.

We discovered too, regrettably, that my old Moonraker rotator is kaput, and had to make the decision to erect the hexbeam on an armstrong rotator for the moment. (For non hams, this simply means the pole is manually rotated, using just the strength of one's arm!!)

The whole operation took about four hours, with tea breaks! It was a lovely sunny day which made it easier and we got to work on our sun tans too HI! The hexbeam is lighter than the MA5B, and without the weight of the rotator the new structure does not need stay wires.

Upon completion, we did the SWR test. SWR is flat across the 20m band, and is around 1.5 - 1.7 on 17m, 15m and 12m. It is a bit high, inexplicably, on 10m, but at 3:1 the ATU will tune it and also the Acom 1000 will handle it if needed.

Who's a happy boy then?

Although band conditions have not been great since it was erected, I worked a good bit of DX yesterday evening and last night, and was impressed with the many 59+ signals I was seeing on the FT-1000MP. Here is a summary of DX worked:

Japan 20m CW 400 watts

Asiatic Russia 20m CW 400w

Sumatra (YB4) 15m SSB 400w

India 15m CW 100w

Svalbard 17m SSB 100w

Swaziland 15m SSB 100w

Tanzania 10m SSB 400w - new country on 10m!!

Few Stateside QSOs on 15m CW 100w

Dominican Republic 15m SSB 100w

Peru 12m SSB 400w (new band slot)

Nicaragua 15m CW 400w

Gibraltar 17m SSB 100w

St Lucia 15m SSB 100w

Venezuela 17m CW 100w

6 metre beam installed - just in time for the first opening!

On Saturday I finally upgraded my 6 metre (50 Mhz) antenna. I have been using a simple aluminium dipole since the sunmer of 2010. It has served me well, giving me 54 DXCCs over two seasons. But I have been hungry for something with a little more gain so that I might notch up some new DXCCs this year. So when I chanced upon a three-element beam for 50 Mhz I snapped it up! Tony EI4DIB and Jim EI2HJB, who have been involved in so many antenna installations at my QTH, made themselves available on Saturday afternoon and we set to work. It was cold and windy but sunny. So typical Irish weather !

This was not a complicated installation in that we were swapping out a 6m dipole with a beam, so we could use the same coax. We were also swapping my 4m folded dipole for a 4m dipole made from my recycled 6m dipole shortened down. Tony and Jim managed to get the SWR of the beam between 1.5-2 so that was fine. It is under the 2m XY beam on the same rotator. I am now well set up for VHF activities!

This afternoon, Sunday, the 6 metre band opened for the first real Sporadic E opening of the year. Very timely too! I put the beam through its paces. I worked a number of stations in Poland and Lithuania and Latvia. Some of the signals were very strong indeed. I was delighted. Below is a video of me working SP3OCC, Ted in Poland, on SSB. I had just worked him on CW. He was 10dB over 9 at times. Very strong.

Below are maps from DX Sherlock showing just how active the band was today. It really opened up for a while in Europe, although the openings to EI were limited along a narrow path to Poland and the Baltic area.

Activity was intense for a time on 50 Mhz

This was an unexpected opening, especially such a big one. My first QSO of the E season in 2011 was on May 1st, so we are just a few days short of that date and the band has opened properly for the first time. While 50 Mhz was active last summer there wasn't so much DX to be worked so we are hoping that this year there will be some new countries floating around. And with the three-element beam now instead of the dipole, here's one op who's chomping at the bit for some extra DXCCs! Happy DXing . . .
