Large Iron Magnetic Core 1:1 RF HF Choke Balun rated to 2000w on CW and much more on SSB mode.

 

Made out of Magnetic real IRON Large Cores Diameter: Approx. 11cm and designed to work at 1-30mhz on HF shortwave bands.

 

Suppresses common-mode currents, effectively reducing electromagnetic interference in equipment.

Made with high-quality imported magnetic core, carefully wound for long-lasting durability.

Equipped with Male M and Female M connectors for easy serial connection between radio stations and feed lines.

 

Key Features & Use Cases
  • Function: Used in amateur (ham) radio setups to suppress common-mode currents, block RF feedback, and reduce electromagnetic interference (EMI) across high-frequency (HF) bands (typically 1.8–30 MHz)
  • Design: Features a 1:1 current balun configuration wrapped tightly around a ferrite/magnetic core.
  • Connectors: Equipped with standard RF coaxial connectors on each end for inline insertion between the transceiver/feeder line and the antenna (such as end-fed or dipole setups)
