My 2nd activation of DL/AL-077
1 CW QSO on 20m, 3 CW QSOs on 40m
Condx ok but only four random QSOs because RBNhole didn’t spot me on SOTAwatch.
Rig: MTR3B / 3W, 1250mAh LiPo, Palm Pico Paddle
Ant: EFHW Dipole as inverted L on 6m GRP Pole
Wx: Sunny (first, later overcast), approx. 5°C
Walking time approx. 3 hrs. up, 3 hrs. down (via „Kleiner Daumen“). Tough conditions due to deep snow.
How to get there?
From Hinterstein (car park) to Giebelhaus by Bus. From there in approx. 1 hour to Schwarzenberghuette (1380m asl).
Follow the signposts to Engeratsgundsee, Laufbichlsee and Großer Daumen (approx. 3 hrs.)
A delta loop antenna is not particularly suitable for SOTA. It requires much more space than a vertical and the set-up is more complicated.
Nevertheless I’d like to show this design here because sometimes space (and weight) don’t matter and a low take off angle is welcome. One possible scenario could be the VK/ZL/JA <> EU S2S event.
While searching for an alternative to my Linked- Dipole I tripped over the posting of Pedro, CT1DBS, illustrating an end-fed half-wave (EFHW)- Dipole with Traps. Here is the Link to his article. With this design changing bands can be done in no time thaks to the traps. Lowering or modifying the antenna is no longer necessary.
