We decided to end the activation, but a look at sotawatch revealed some USA stations nearby on 20m.Д«oth Jorge and me worked S2S both K2JB (W4C/WM-058) and NY4G (W4T/SU-042), great! Jorge had worked a big number of EU chasers and even K0RS and NE4TN himself.Д 5 IMG_20190329_174558.jpg 4160Г—2336 3.68 MB I tried to work for some minutes N3II/P wich I received ok a little up, at 14.062,5, but he didnвЂ™t hear me, a pity! In the other hand I got a call from LA1KHA/P S2S, thanks Kjell!ДЄfter 1 hour calling on CW, I was tired and wind was developing. Well, it did! My logbook shows 7 qso with regular North american chasers (state & received reports shown), apart from some EU chasers: I had the monoband antenna so I stick with 20m, CW for most of the time. Jorge run first on 60m, then 40m, 30m and 20m a few minutes at the end. As said, the Delta was not as high over ground as planned. In the other hand, I had about 2 вЂ“ 3 dB better than Jorge on NA. It had sense bearing in mind the F/B in my antenna. We did so for about 5 minutes, This is the data I got after returning home and checking the Internet:Дata confirmed Jorge had better signal towards EU: 9 dB better than me on OH. Then we settled our rigs (KX2 & KX3) to 10 w output power and started sending a beacon.

It is difficult to deploy two full size loops on ground and then to raise the pole without having some troubles with tangled wires, specially if wind is present.

Jorge helped me to install the antenna which took about half an hour. Weather was okay on top, clear sky, but a bit windy. We would run the first minutes calling as a beacon (/B) to see our signal level on automatic decoder stations afterwards (RBN network). Jorge EA2LU was kind to join me and we agreed to run a brief test with the antennas prior to activating the summit. Target: compare my 2 element Delta loop with a End fed Half wave and check it it produces any DX. Let me introduce the 2BD (2 element Delta beam) aerial. It seemed to be okay so I decided to give it a try for the first time on a summit. Last week I cut long wires at home (this can be a bit annoying for the family in the living room, hi) and tested briefly the resonance in a park. I had enough reasons to decide it was time to try that in the real life. It exhibited up to 5,5 dBd in its optimum design and 10 dB Front/Back.

It required a single vertical support pole plus 4 guying cords.

It was a novel design based on 2 element Delta loop.

What were the key features of this antenna? I optimised the model doing modifications until I achieved the best performance. I run different alternatives and then one atracted my attention. My head was thinking and I decided to run some simulation models (Mmana) with ideas I had. It worked great but scaling that beam to 14 MHz is huge and that band is pretty closed nowadays! We wonвЂ™t have towers and rotors there, what should I do? I recalled a past experience when I built a vertical Moxon antenna (2 element) made with wire elements for 21 MHz. I settled my target for 14 MHz, a good choice nowadays to get some DX during daylight. Well, it sounds good but it is a bit difficult. As for me, building and testing antennas is one of the most interesting parts of our hobby,ДЄ good way to increase the chances for DX would be to design a beam antenna for the countryside. It is time to find a new way to improve the signal when portable. These days, propagation conditions are rather poor.
