FSR-A · Counterpoise & Radials
A radial or counterpoise component for documented unbalanced antenna configurations.
Why operators make room for it
Build repeatability underneath an unbalanced antenna
A field antenna is not complete simply because the vertical element is standing upright.
The CHA FSR-A is the same precision-machined stainless steel coupling adapter included with the CHA FSR — Faraday Strip Radial System , now available separately for operators who want maximum flexibility in the field.
The operator gains a deployable, understandable ground-side system that can be laid out consistently and adjusted only where the official antenna configuration permits it. The specifications below show exactly where CHA FSR-A fits in that plan.

CHA FSR-A (Adapter)
Special Stainless Steel 3/8-24 Coupling Adapter
The CHA FSR-A is the same precision-machined stainless steel coupling adapter included with the CHA FSR — Faraday Strip Radial System, now available separately for operators who want maximum flexibility in the field.
Designed for universal compatibility with 3/8-24 antenna systems, the CHA FSR-A allows you to securely “sandwich” accessories, counterpoise systems, Faraday strips, grounding plates, or custom mounting solutions between your antenna and mount system. The adapter features a rugged stainless steel construction engineered for portable, mobile, base, emergency communications, POTA, SOTA, and military-style field operations.
The bottom side features a male 3/8-24 thread, while the top side provides a female 3/8-24 connection, making it compatible with virtually all Chameleon Antenna vertical systems and accessories including the CHA HYBRID, CHA HYBRID-MINI, CHA HYBRID-MICRO, CHA MCC, CHA BLANK, CHA SS17, CHA SS25, CHA MPAS, CHA TDL, and many other industry-standard 3/8-24 antenna components.
Built from corrosion-resistant stainless steel, the CHA FSR-A is designed to withstand harsh outdoor environments including rain, salt air, mud, dust, and extreme temperatures. The compact low-profile design maintains excellent mechanical strength while minimizing unnecessary height or instability in portable deployments.
Whether you are building a custom counterpoise system, integrating Faraday radial strips, experimenting with grounding configurations, or creating a modular antenna platform, the CHA FSR-A provides a professional-grade solution trusted in demanding field conditions.
