Portable with my ham friend Chris,OE5CCN(he took the picture), using 200w and a cubical quad for 10m during the Oceania Contest, 1000m above sea level.What a great day!!
Ultrabeam UB-50-3 element dynamic yagi from 10-20m, rotary dipole for 30/40m (U shape).
I put up a sloping delta loop for 40m.The delta loop is fed in the corner, favouring Europe a bit and it´s very interesting to switch among the oblong, the delta loop and the rotary dipole. The rotary dipole is the best antenna on 40m. Sometimes there is hardly any or no difference, but sometimes the dipole is 3 to 6db stronger than the other wire antennas, depending where the signal comes from.
Oblong for 80m.I found the design in a Swiss antenna book. The top wire is up about 8m, the bottom wire about 3m, so the vertical section is 5m.At first I fed it in the middle of the vertical section, but I wasn´t happy with the results, the antenna was very noisy!I always thought a loop antenna is a quiet antenna. I haven´t found any information about this in antenna books, but a friend pointed me into the right direction.ON4UN says that a vertically polarized loop is an array of 2 phased verticals. EU was down as expected, because of the vertical polarization and dx wasn´t that strong.Please keep in mind that our mountains are really high and the waves have to get over them!
Now I feed it in the bottom corner. I´ve good swr in the cw portion of the band, but I need a tuner at the top end. The results were ok, but not superb, as I had hoped for. Next year I plan to put it up as a delta loop and see if it is any better.
I put this antenna up during a field day and I could use it on many ham bands with good results.There is a 2: 1 balun and I feed it with coax.
GP for 2m/70cm, above the beam.
View to the southeast, long path to W6/7.As you can see on this picture, an antenna with a very low take off angle is not a benefit in this valley- but I do get out, even with low dipoles on 40 and 80m.
Next to this mountain in the background, on the right hand side, is the home of our 2m FM repeater OE5XKL(Krippenstein) on 145.712.5-Echolink international:534058.
It´s not only an ordinary mountain but also a great freeride skiing area.
Living menu on an alpine meadow! I took a photo of one cow only, but there were many others offering all kinds of drinks or food.
