1000W 3-in-1 Shortwave Common Mode Filter, 1.8-54MHz Waterproof RF Choke, Choke Coil Magnetic Ring 50dB Attenuation, 50Ω Impedance, 0.3dB Insertion Loss, SWR<1.2 for Amateur Radio Outdoor Use

RBR1000W Frequency: 1.8–54MHz Power (PEP): 1000W Impedance: 50Ω Common Mode Attenuation: 50dB Insertion Loss (28MHz): 0.3dB Connector: M-J Functions: RF Choke, RF Ground, BPF, Waterproof, Anti-static

• 1000W Full-Scenario Power：With 1000W PEP power rating, it is compatible with indoor fixed radio stations and outdoor medium-power shortwave communication, meeting ham radio operators' daily communication and field antenna setup needs, and serving as the main model for multi-scenario amateur radio use
• 3-in-1 Strong Protection：Integrates common mode filtering, grounding terminal and band-pass filter, accurately blocks common mode current (avoids equipment interference/damage), filters out-of-band clutter, and achieves effective grounding to dissipate noise, providing all-round protection for shortwave radio equipment
• Efficient Safe Communication：Eliminates antenna static electricity, electrically isolates antenna and feedline, improves RF radiation efficiency, eliminates RFI interference in radio shacks, and maintains the radiation pattern of directional antennas. It not only optimizes transmission/reception quality but also ensures outdoor operation and equipment safety
• Waterproof Outdoor Use：Equipped with an integrated waterproof and sunproof housing, the connector adopts a professional waterproof design. It is resistant to wind, rain, sun and other complex outdoor environments, can be directly installed at the outdoor antenna feed point, and maintains stable performance without aging for long-term use
• Flagship RF Performance: Operates across the 1.8-54MHz band with a 50Ω impedance and 50dB attenuation. It ensures low-loss transmission of effective signals while significantly reducing the noise floor and RF interference
