Hf Common Mode Choke 1:1 Current Balun 1.8 30MHz Shortwave Choke Magnetic Ring

Feature: 1. Full HF Band Coverage: This HF common mode choke current balun is specifically engineered to cover the entire 1.8 30 MHz shortwave spectrum, supporting all amateur bands from 160 meters to 10 meters for versatile operation. 2. Digital Mode Optimized: The shortwave choke magnetic ring is designed for high duty cycle modes like FT8 and JS8. It effectively suppresses common mode currents to prevent PC USB disconnections, system freezes, and touchscreen malfunctions during high power transmission. 3. High Power Handling: Rated at 200W for CW and SSB, this HF common mode choke current balun handles a tested peak power of 350W on FT8. The generous power margin keeps the core unsaturated during prolonged transmission. 4. Premium Core and Wiring: This shortwave choke magnetic ring utilizes a high grade imported ni zinc ferrite core (50mm OD 30mm ID). It is wound with RG58 flexible coax cable to ensure low loss at high frequencies and easy routing in tight spaces. 5. Direct In Line Connection: Featuring a PL259 male to SO239 female design, this common mode choke current balun connects directly between your radio and antennae feedline. Pure copper connectors with hand soldered joints ensure minimal contact resistance for lasting durability. Specification: 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 peak) Core Outer Diameter: Approx. 50mm 1.97inCore 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 RTTY.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 Note:
