Force 12 From Santa Cruz

In an attempt to improve his antenna situation my dad, KD6EUG, was perusing Craigslist and found a seller in Santa Cruz that was looking to part with his Force 12 Sigma 5. I had just been reading about this antenna on one of NE1RD’s blog’s:The 100lbs DXpedition. Scott used his Sigma 5 on a few DXpeditions and reported good results. The Sigma 5 is a 5 band (20-17-15-12-10) vertical dipole. This should be easy for my dad to setup at the home QTH in San Jose, CA and also up at the cabin in the Sierras. I also have high hopes that this antenna will allow for an HF QSO between my dad and me. And a big thanks to Jack, WA6FYD who was the previous owner of the Sigma 5. I got to exchange emails with Jack – he’s retired military and a devoted CW aficionado.


  1. Hi,
    Never have seen such an antenna before. Saw your dad at late coffee today and he was excited to tell me about it. We have a tentative schedule for some time this Sat on 20 meters. We will see how it goes.
