CHA WARC-D Product DNA: Complete System Overview

CHA WARC-D gives LEFS 4010 owners three dedicated resonant dipoles for 30, 17, and 12 meters when a focused WARC-band antenna is more useful than forcing a tuner to solve every band.

Start with the operator’s decision: CHA WARC-D gives LEFS 4010 owners three dedicated resonant dipoles for 30, 17, and 12 meters when a focused WARC-band antenna is more useful than forcing a tuner to solve every band.

How this exact system works

It contains three separate single-band wire pairs—not one linked or simultaneous three-band radiator. The selected pair attaches to the DIPOLE wing nuts and uses the DIPOLE BNC feed. Treat the product as a complete documented system: feed point, radiator, return or balanced second leg, feed line, support, geometry, power, and environment all matter.

The boundary that prevents mistakes

Never mix legs from different pairs or call WARC-D LINK-D. Current privileges, band plans, propagation, and site rules remain operator responsibilities.

Use this field sequence

Choose and label one matched pair, install it horizontally or as an inverted-V, keep unused pairs packed, support the center without coax load, and verify SWR in final geometry.

Source boundary

CHA LEFS 4010 User Guide 250609. The exact current product, components, band, feed, support, geometry, and operating limits control; physical fit does not establish compatibility.
