HF Common Mode Choke Balun 1.8 to 30MHz Shortwave Choke Magnet Ring 1:1 Current Balun with M Connector

Feature: 1. Frequency Coverage: This HF common mode choke operates effectively across the entire 1.8 to 30 MHz shortwave spectrum, covering all amateur bands from 160 meters to 10 meters. It ensures reliable performance for various communication needs without any gaps in frequency response. 2. Digital Mode: Designed specifically for high duty cycle digital modes like FT8, JS8, and WSPR. This shortwave choke balun effectively suppresses common mode currents, eliminating issues such as USB device disconnections, computer freezing, and erratic touchscreen behavior during high power transmissions. 3. High Power: Rated at 200W for CW and SSB, this 1:1 current choke balun can handle up to 350W in real world FT8 testing. The ample power margin ensures the ferrite ring remains cool and unsaturated during extended full power operation, delivering consistent signal transfer. 4. Excellent Construction: The cores of this 1.8 to 30MHz choke magnet ring are made from imported Ni zinc ferrite material, measuring 50mm outer Diameter and 30mm inner diameter. This provides excellent frequency characteristics with minimal loss, while the RG58 coax cable is flexible and maintains stable impedance for easy installation. 5. Convenient Connectivity: Featuring an M male to M female connector design, this HF choke magnet ring connects directly between your transceiver and antennae feedline. The pure copper connectors are hand soldered for minimal contact resistance, Specification: Item Type: HF Common Mode Choke Balun Frequency Range: 1.8 to 30 MHz Power Handling: 200W (CW, SSB), 350W (FT8 measured peaks) Cores Material: Ni Zinc FerriteConnector Material: Copper Outer Diameter: Approx. 50mm 1.97inInner Diameter: Approx.30mm 1.18in Feedline Type: RG58 Super Flexible Coax Connector Type: PL259 (UHF Male) Input, SO239 (UHF Female) (Output) Applicable Scenarios: Digital Communication: High duty cycle modes such as FT8, JS8, WSPR, and support for RTTY. Interference Suppression: Address the issue of shortwave radios transmission interfering with peripheral devices such as computers, USB hubs, automatic tuning stations, and switching power supplies. Antennae Feed Optimization: Applicable to unbalanced antennae systems (such as long line antennaes, end feed antennaes, and GP antennaes), it effectively blocks the common mode current on the outer sheath of the feed line, reduces background noise, and enhances signal purity..
