I go lighter and lighter and lighter... I've built a new EFHW wire for my SOTA-activations last weekend. The antenna is "linked" and is full halfwave on 40/30/20/17m. I went from 0,75mm² (~18 AWG) to 0,14mm² (~26 AWG). Thank you Andreas, DB2AJ for the hint. That saves some additional weight. I use this thin wire together with my homebrew EFHW-QRP tuner. I use a pair of 2,6mm "Zwerg-Stecker" and "Zwerg-Kupplung", with the plastic housing removed, for every link. For optical reasons and also for more mechanical stability, I added som heat-shrinking tube to the connectors. The wire-winder came from SOTAbeams UK and they fit perfect to this easy construction. The whole job did not take longer than about 60 minutes.
