CHA LEFS FEATHER Engineering and Performance Guide

CHA LEFS FEATHER performance comes from the complete current path and installed geometry; matching is only one part of the result.

Start with the operator’s decision: CHA LEFS FEATHER performance comes from the complete current path and installed geometry; matching is only one part of the result.

How this exact system works

The system combines a 49:1 End Transformer Unit, BNC female feed, 61½-foot high-visibility 26-gauge PTFE braided-Kevlar wire, integral line winder/end insulator, S-Biner strain relief, and a field-tuning stub. Paracord and coax remain station equipment.

The boundary that prevents mistakes

Published power is 25 W SSB and 10 W CW or digital. The guide lists 40, 20, 15, and 10 meters without a tuner; 30, 17, 12, and the upper 10-meter FM segment require a tuner. This guide documents a sloper, not a generic horizontal/NVIS configuration.

Use this field sequence

Record frequency, resistance and reactance, geometry, height, feed line, ground, nearby structures, power and mode. Change one variable at a time and never translate a low SWR into an efficiency or range claim.

Source boundary

CHA LEFS FEATHER Operator’s Manual, Rev. 3/30/2026. The exact current product, components, band, feed, support, geometry, and operating limits control; physical fit does not establish compatibility.
