SOTA EF KEVLAR ANTENNA QRP 9:1 10 WATTS

QRP EF ANTENNA WITH KEVLAR WIRE

A multi band antenna covering 80 to 10 meters with a tuner.

The impedance transformer (9:1) feeds the end fed half wave wire close to a 50Ω (unbalanced) coaxial input. 10 watts pep

Kevlar wire is used on this antenna this makes the antenna light weight yet strong.
