JA/VK/ZL – EU S2S Party from DM/BW-089 – Farrenberg – 820m


October 21, 2017: 6:00 – 7:45 UTC

Rig: K3 / 100W, Varta LA60 (60 Ah) AGM- battery, Begali „DXpedition“ paddle

29 CW QSOs on 20m – 7 S2S- QSOs but none with JA/ VK/ ZL this time.


Delta Loop for the 20m band

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.

Delta Loop on HB0/Li-004, Augstenberg, 2359m a.s.l. during our DX-pedition to the Principality of Liechtenstein in September 2013. DL4AAE worked many JA’s on 20m with 100 Watts output power.  Note: the horizontal wire has been attached to the pole in order to avoid sagging.


EFHW- Dipole with Traps

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.
