Chameleon Antenna CHA-Blank Antenna Mount Adapters support the CHA-SS58, CHA-SS17, and CHA-SS25 whips, allowing users to select the best configuration for their needs. Whether you need a compact setup or an extended-range solution, these adapters provide flexibility for various HF band applications. The modular design lets operators customize their antenna system based on specific mission requirements and operational conditions.

CHA-Blank Features and Benefits

• 3/8" x 24 Threaded Connection: The CHA BLANK’s threaded connection enables secure attachment of compatible whips like the SS58, SS17, and SS25, ensuring a stable and reliable setup in any configuration.

• Coaxial Adapter Options: Features either an SO-239 female or BNC female connector, allowing easy integration with different types of coaxial cables and RF equipment.

• Base and Radial Support: When combined with the CHA-PUCK-HUB, the CHA-BLANK supports up to six radials using Banana Jacks. Radials enhance the antenna’s efficiency by completing the ground circuit for unbalanced antenna designs like vertical whips, improving SWR and overall performance.

• Versatile Configuration Options: Depending on the whip used, the CHA BLANK allows operators to tailor their setup for various band conditions and operating environments. For instance, using the CHA SS17 and CHA M-COIL, operators can cover the 30 and 40 meter bands, ideal for longer-distance HF communication. The shorter SS58 provides a more compact option while still performing well on upper HF bands.

• Enhanced Portability: The CHA BLANK and compatible whips offer quick setup and breakdown, making them suitable for operators who frequently move locations or need a lightweight, transportable solution.

• Optimal SWR Tuning: The CHA BLANK enables precise tuning through whip adjustments and radial length modifications, ensuring a low SWR across the chosen operating band. This is particularly useful for portable operations where site conditions, nearby objects, and ground conductivity might affect resonance.
