상품 특징

• 2000W High Power: Exclusively designed for 2000W high-power fixed shortwave radio stations, professional ham radio setups and long-distance communication, it can carry high-power RF signals and meet the high-power transmission needs of professional amateur radio operations
• 3-in-1 Core Function: Integrates common mode filtering, grounding terminal and band-pass filtering, effectively blocks strong common mode current in high-power systems, avoids interference/damage to valuable radio equipment caused by high-power common mode current, filters clutter and dissipates noise energy safely
• Flagship RF Parameters: Covers the full 1.8-54MHz shortwave band with 50Ω standard impedance for perfect matching with high-power coaxial feedlines. At 28MHz, it has only 0.3dB insertion loss, SWR<1.2 and 50dB common mode attenuation, ensuring low-loss transmission of high-power signals and greatly reducing noise floor and distortion
• Industrial Waterproof & Sunproof：Equipped with a thickened waterproof and sunproof housing, the connector features industrial-grade waterproof design, resistant to sun, rain and outdoor corrosion. It can be permanently installed at the outdoor antenna feed point, working stably in all weather conditions, suitable for field fixed stations and base station-level use
• Professional Communication Benefits: Efficiently eliminates antenna static electricity, achieves strong electrical isolation between antenna and feedline, maximizes RF radiation efficiency, completely eliminates RFI interference in radio shacks, and accurately maintains the designed radiation pattern of directional antennas. It keeps high-power RF energy focused on antenna radiation, realizing long-distance, high-clarity and interference-free professional shortwave communication
