Package List: 1 x Shortwave Choke Magnetic Ring​ 1 x Instruction Manual Notice:

• Common Mode Suppression: Shortwave Choke Magnetic Ring effectively blocks common mode currents across the 1.8-30MHz spectrum, eliminating RF interference to ensure clear communication signals during ham radio operations.
• High Power Handling: This 1:1 current balun supports up to 100W PEP (EM25 model) with a 200W withstand power, utilizing high permeability ferrite that resists saturation and maintains stable impedance under high temperature conditions.
• Plug and Play Setup: Equipped with an integrated M male to M female connector, this HF choke coil installs directly inline without extra cables or soldering, saving setup time for field and base station use.
• Compact & Rugged Build: Featuring a 45mm diameter magnetic ring, this common mode choke fits portable radio kits while delivering lasting mechanical stability in harsh outdoor ham environments.
• Broad Frequency Consistency: Maintains uniform suppression performance from 1.8MHz through 30MHz, making it suitable for multi-band HF operations including contesting, DXing, and emergency communication scenarios.
