Fafeicy HF Common Mode Choke Current Balun, 1.8-30MHz Shortwave Choke Magnetic with PL259 to SO239, for 200W CW SSB FT8

Spec: Item Type: Hf Common Mode Choke Current BalunCore Material: Ni Zinc Ferrite Frequency Range: 1.8-30 MHzPower Handling: 200W (CW/SSB) / 350W (FT8 measured ) Core Outer Diameter: Approx. 50mm / 1.97in Core Inner Diameter: Approx. 30mm / 1.18in Feedline Type: RG58 Super Flexible Coax Connector Type: PL259 (UHF Male) Input, SO239 (UHF Female) Output Application: 1. Digital Communication: High duty cycle modes such as Support for FT8, Support for JS8, Support for WSPR, Support for .2. Interference Suppression: Eliminates interference to computers, USB hubs, automatic antennae tuners, switching power supplies, and other peripheral devices caused by HF transceiver emissions. 3. Antennae Feeder Optimization: Suitable for unbalanced antennae systems (e.g., long wire antennas, end fed antennas, ground plane antennas). Effectively blocks common mode currents on the outer surface of the feedline, reducing the noise floor and improving signal clarity. Package List: 1 x HF Common Mode Choke Balun How To Use: Direct installation and use.

• [FULL BAND COVERAGE FOR VERSATILE OPERATION] This HF common mode choke current balun is expertly designed to cover the entire 1.8 30 MHz shortwave spectrum. It provides robust support for all amateur radio bands from 160 meters down to 10 meters ensuring you stay connected across a wide range of frequencies for diverse operating conditions and preferences.
• [HIGH DUTY CYCLE PERFORMANCE FOR DIGITAL MODES] Engineered for demanding digital modes like FT8 and JS8 this shortwave choke magnetic effectively suppresses common mode currents. It reliably prevents PC USB disconnections system freezes and touchscreen malfunctions even during sustained high power transmissions giving you a stable interference free digital experience.
• [POWERFUL AND RELIABLE POWER HANDLING] Rated at 200W for CW and SSB this HF common mode choke current balun handles a tested power of 350W on FT8. The generous power margin keeps the core unsaturated during extended transmission periods ensuring consistent performance and protecting your valuable equipment from potential damage.
• [PREMIUM MATERIALS FOR LOW LOSS AND DURABILITY] Utilizing a high grade imported ni zinc ferrite core measuring 50mm OD and 30mm shortwave choke magnetic is wound with RG58 flexible coax cable. This combination ensures low signal loss at high frequencies and allows for easy routing in tight spaces around your shack for a clean installation.
• [DIRECT CONNECTION WITH PURE COPPER CONNECTORS] Featuring a PL259 male to SO239 female design this common mode choke current balun connects directly between your radio and feedline. Pure copper connectors with hand soldered joints ensure minimal contact resistance for lasting durability and a reliable connection that you can count on for years to come.
