I am a fan of Chameleon Antennas. I already own several and have another on order. I like them because they work as advertised and are exceptionally well made. If I need to rapidly deploy a field station that I am confident the Chameleon's will do the job irrespective of conditions. The L.E.F.S antenna is so named because it is a Light End Fed Slopoer. It is designed to be a be used without a tuner on multiple bands. In the video Julian OH8STN puts the antenna through it's paces. I think you can see how such a versatile and usable this antenna could be in a temporary emergency field station.
