Chameleon Single Extension

Overview

Chameleon Antenna SINGLE EXTENSION is a modular length section for MPAS-style antenna builds, designed to increase radiator length without sacrificing portability. Adding physical length helps you optimize resonance and overall efficiency—particularly when operating portable on lower HF bands where additional radiator length can produce meaningful, real-world improvement.

Key benefits

• MPAS-ready modularity: Extend your build while keeping it quick to assemble, break down, and reconfigure in the field.
• Better tuning flexibility: Added length helps you fine-tune mechanical length to match band plans, site constraints, and your coil/whip combination.
• Lower-band advantage: Increasing radiator length can improve results on bands such as 40 m and 30 m (final performance depends on your complete setup, including matching and counterpoise/ground).
• Outdoor durability: Constructed from anodized aluminum and stainless steel for repeated field use.

Compatibility

Chameleon Antenna SINGLE EXTENSION is designed for MPAS component stacks and other compatible systems using the standard 3/8″ x 24 threaded interface, including builds that use the BLANK ADAPTER and common MPAS whip options.

Typical placement in a build

Install Chameleon Antenna SINGLE EXTENSION between the BLANK ADAPTER and your chosen whip to extend effective radiator length while keeping the system modular and easy to adapt on site.
