Operating location from a top in alps c2600m
Now this was a perfect SOTA location, I stayed on top overnight and used the flag pole to my right to support a 40m/20m dipole, you can see the fixture I connected to, the little ring clamp, as soon as the cable car stopped for the night out came the radio gear, it even snowed! If I had taken 2m yagi would have been amazing location as line of sight was > 80miles, the Eiger and Jungfau (Bernese Oberland group) are in the photo over my right shoulder. Temp dropped to below minus 15 but the morning operating the grey line was fun 100 or so QSO SSB qrp as HB9/M1KTA/P.
