It’s the perfect companion for the CHA SS25 25-foot telescoping whip and seamlessly integrates with your MPAS-ready Basic Vertical configuration to create a resonant, quarter-wave, base-loaded vertical antenna on 40 meters.
Built with serious operators in mind, this coil brings simplicity and performance together—whether you're in the field, on a deployment, or operating under HOA restrictions.
