Featuring a ferrite sleeve and 50 ohm impedance, it reduces feed-line radiation and RF feedback for HF/VHF amateur radio systems. Compatible with PL-259 to SO-239 connectors, it’s perfect for fixed, mobile, and portable stations, enhancing signal clarity without tuning or impedance matching. ## Description Designed to help reduce unwanted common-mode current in compatible 50-ohm HF antenna systems. Compact for portable, mobile, and fixed amateur radio applications. The GRA-RWSM is designed to help suppress common-mode RF current on the coaxial feed line. It helps reduce unwanted feed-line radiation and RF feedback, but it is not an antenna tuner or a general-purpose noise filter. Results vary depending on the antenna system and the source of RF noise. Compact size for portable HF operation. Easy to integrate into temporary HF stations. Compact design for HF antenna systems. Pairs easily with portable HF radio equipment for field operation. Designed with a serviceable threaded connector construction that allows inspection when needed. Before operation, ensure all threaded sections are correctly assembled and fully tightened. Q1. Is it normal if the PL-259 connector can be separated? Yes. The connector uses a serviceable threaded construction. Threaded sections may be separated for inspection or service and are not, by themselves, an indication of a defective product. Q2. What should I check before using the product? Ensure all threaded sections and external connections are correctly assembled and fully tightened before operation. Q3. How should I install or remove the choke? Hold the connector body or fixed section during installation or removal. Avoid twisting, pulling, or rotating the coaxial cable or product body. Q4. Can I disassemble the connector? Disassembly is not recommended unless inspection or service is required. If disassembled, verify that all internal components are correctly positioned before reassembly. Q5. What if the RF connection becomes intermittent or SWR suddenly increases? Stop transmitting immediately, power off the equipment, and verify that all threaded sections and external connections are fully tightened. If the issue continues after reassembly, discontinue operation.
