Its high-efficiency impedance matching network transformer (49:1), ultra-thin 20 gauge antenna wire, and micro-size RG-316 coaxial cable (Optional) establish the LEFS 4010 as the perfect companion for pocket-sized QRP (LOW-POWER 100W SSB & 50W CW & 25W DATA) transceivers. Installation is a breeze, with no need for a tuner or ongoing adjustments on the entire 40, 20, 15, and 10 meter ham bands (extendable to 30, 17, and 12 meters with a tuner).

When it's time to hit the trail, you'll appreciate the LEFS 4010's space-saving design.
