SOTA HWEF KEVLAR ANTENNA QRP 49:1 10 WATTS

QRP HWEF ANTENNA WITH KEVLAR WIRE

A 4 band antenna covering 40 / 20 / 15 and 10 meters.

The impedance transformer (49:1) 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.
