Unlock the Power of 40 Meters with Your Basic Vertical (BV) Setup

The CHA M25-Coil is a rugged, high-performance 40-meter loading coil designed to dramatically expand the frequency coverage of your vertical antenna system. 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.

 

Key Highlights

  • Enables 40M Operation: Add the critical 40-meter band to your vertical antenna setup without changing your configuration.
  • Bypass Feature: Switch instantly to 30–6M operation with a jumper (jumper not included)—no need to remove the coil.
  • Purpose-Built for SS25: Optimised for the CHA SS25 25' telescopic whip for perfect matching and performance.
  • MPAS-Ready: Fully compatible with Chameleon Antenna’s Modular Portable Antenna System (MPAS).
  • Quick Deployment: Simple, tool-free installation ideal for portable, base, or emergency setups.

Durable and Compact: Built in Nevada, USA for field-grade reliability.
