Chameleon Antenna: CHA BLANK Adapter, BNC

The CHA BLANK is a foundational and highly adaptable component within Chameleon Antenna’s portable antenna systems, providing versatility by supporting the CHA SS58, CHA SS17, and CHA SS25 whips. These options enable users to choose the best configuration for their needs, from compact setups to extended-range solutions.

CHA BLANK Features and Integration

• 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: Converts to either an SO-239 or BNC connection, 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.

Benefits of Using the CHA BLANK with Each Whip

• 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.

Example Setups with the CHA BLANK

Compact Setup with CHA SS58:

• Ideal for short-range HF communication on higher bands like 20, 15, and 10 meters.

• The SS58 is compact and easy to deploy, making it suitable for fast setups in environments where space is limited.

Extended Coverage with CHA SS17 and Loading Coil:

• This setup supports a broader frequency range, enabling operation on 30 and 40 meters by adding the Medium Loading Coil.

• The SS17’s length helps achieve stronger signal strength, making it suitable for moderate-range HF contacts.

Maximized Range with CHA SS25:

• The 25-foot SS25 whip provides the highest efficiency and longest-range capabilities for the CHA BV configuration.

• This setup is recommended for users who need reliable, long-distance communication or for emergency response scenarios where maximizing signal strength is crucial.
