CHA ABR-400 RADIATORS

CHA ABR-400 RADIATORS

High-Performance, Low-Loss Radiators for Serious Operators

The CHA ABR-400 Radiators are premium-grade, ultra-low-loss coaxial radiators designed for maximum performance in demanding portable and fixed HF antenna setups. Engineered with precision and durability in mind, these radiators are available in two lengths—102 inches and 145 inches—to provide unmatched versatility for your operating style and environment.

Each radiator is custom-manufactured exclusively for Chameleon Antenna by ABR Industries—a trusted leader in coaxial cable production (abrind.com). Built with genuine ABR-400 coax, these radiators deliver superior RF conductivity and extremely low attenuation, which is essential for efficient HF operation.

To ensure optimal performance, both ends of the radiator are pre-shorted at the factory. This design enhances the radiator's ability to act as a highly efficient radiating element, especially important in magnetic loop applications where efficiency and low noise are critical.

Key Features

• Available in Two Sizes: Select 102" or 145" lengths to suit your antenna’s frequency coverage and physical layout.
• Custom Built by ABR Industries: Precision-manufactured in the USA specifically for Chameleon Antenna.
• Ultra-Low Loss: Utilizes authentic ABR-400 coaxial cable for superior signal integrity and minimal power loss.
• Shorted Ends for Maximum Radiation: Factory-shorted ends create a continuous conductive path to optimize radiation performance.

Coupling Loop Compatibility:

• Use a 6" diameter coupling loop with the 102" radiator.
• Use an 8" diameter coupling loop with the 145" radiator.

Weather-Resistant & Rugged: Designed for field use, permanent setups, and demanding portable deployments.

Multi-Application Ready: Ideal upgrade or custom build component for loop antennas like the CHA F-LOOP 3.0 or DIY magnetic loop systems.

Optimize Your Signal

Whether you're operating in a restricted HOA environment, on a remote summit, or from your backyard shack, the CHA ABR-400 Radiators are engineered to give you the edge. Their ultra-low loss construction, paired with the proper coupling loop dimensions, ensures efficient radiation, improved bandwidth, and higher transmitted power—perfect for QRP enthusiasts and serious HF operators alike.

Compatible With:

• CHA F-LOOP 3.0
• Custom magnetic loop builds
• Compact or stealth HF antenna setups

Note: For optimal results, be sure to match the radiator length with the correct coupling loop size:
6" diameter for the 102" radiator, and 8" diameter for the 145" radiator.
