Push your station to the limit with the high-power WOOKLEA 1:1 Current Balun Choke, engineered to deliver pure, noise-free signals for 1.8-54MHz HF shortwave radios. When operating at higher power levels, common-mode currents and EMI can wreak havoc on your entire antenna system, especially during FT8 operations. This heavy-duty choke acts as a definitive barrier against interference. We focus on real, tangible quality: featuring a substantial Nickel-Zinc ferrite core and premium -3 ultra-flexible coaxial cable, built exactly as specified. The pure copper soldered UHF connectors ensure true, efficient signal transfer without cutting corners. Setup is plug-and-play—connect the PL-259 male directly to your radio and the SO-239 female to your feedline or tuner in seconds. Highly resistant to temperature spikes and magnetic saturation, this robust 10.8 oz unit comfortably supports demanding 500W SSB operations. Ideal for serious amateur radio contests, emergency communications, and rigorous field days where reliability is non-negotiable. Stop letting stray RF compromise your performance. Package dimensions: 4.7 x 4.3 x 1.4 inches.
