  • The Chameleon CHA Coax with Integrated RFI Choke is a practical and reliable feedline solution for amateur radio operators who want a quality coax assembly with added common mode noise suppression built in. Available in multiple length options, this configurable coax is ideal for portable, fixed, and temporary station setups where clean signal performance and straightforward installation are important.

    Constructed from 50 Ohm RG-58C/U coax with a stranded centre conductor, each cable is fitted with two PL-259 connectors and features an integrated RFI choke installed at one end of the cable. This helps reduce unwanted RF travelling on the outside of the coax, which can assist with lowering interference and improving overall station performance.

    With a power limit of 300W SSB, the CHA Coax with Integrated RFI Choke is well suited to a wide range of HF and general amateur radio applications. With several length options available, it is easy to choose the version that best suits your station layout and operating requirements.
