Portable operations during the Japan International CW Contest (April 14, 2007)
Portable Operations
From time to time I operate from other locations, either to extend the coverage I get from my home station or just for fun. I usually use a 14MHz end-fed mono-band vertical dipole, made of a coaxial cable and a current BALUN. To support the antenna I use a 12 meters fiberglass pole (Spiderbeam, see pictures).
ON4KNP/A
Once a year I spend a few days in the southern part of the country in village called Alle-sur-Semois. As the garden permits it, I erect a ‘larger’ wire antenna supported by the same 12 meters fiberglass pole.
June 2005: 14MHz vertical dipole.
June 2006: double Zepp 2*20 meters, in inverted-V, tip at 10 meters.
June 2007: G5RV in inverted-V, tip at 10 meters.
OZ/ON4KNP
Last August (2007), I was QRV from a village called Sjølund, near Kolding, on the East coast of Denmark. Activities were exclusively on 10MHz CW, running 50 to 100W into a vertical dipole (first configuration), but as I couldn’t fully erect the antenna, the SWR wasn't that great, so I folded it to get a ground plane. Funny enough, the SWR was decreasing when the soil under the antenna was wet by the rain. I now understand the importance of good radials!
Other locations In the last years, I have been QRV on V-UHF during holidays spent in: W4 / 6 / 7 / 0, KL7 and VE2, but made very few QSO.
