The CHA LEFS is a six-band, no-tuner, High Frequency (HF) antenna for use on the 40, 20, 17, 15, 12, and 10 meter Amateur Radio Service (ham) bands. It is a minimalistic design and lightweight components are intended for the serious backpacker and outdoor adventurer. Leave the tuner and SWR meter at home – just bring a radio and a pair of boots!

The CHA LEFS is designed for the trail. The sturdy line winder with integral high- efficiency impedance matching network transformer, Ultra-thin 20 gauge PTFE antenna KEVLAR wire, and 50 feet of lightweight Micro 90 paracord enables highly portable six band operation without the extra bulk of an antenna tuner.
