Antenna is a half wave antenna with Kevlar wire.
An impedance transformer (49:1) to feed a high impedance, end fed (unbalanced) random wire which is likely to be a few hundred ohms, and transform it into something closer to a 50Ω (unbalanced) coaxial input. 100 watts
This is a unun ( unbalanced to unbalanced ) transmission line transformer designed to match 2500Ω to 50Ω .
Technical specification :
Wire is Kevlar 1.5mm which is lite and supple to use. The overall lenght of the wire is 5 metres so it is ideal to use with a small portable mast for field days.
