Comet TRF-MINI HF/6m RFI Choke 1–55 MHz Inline Noise Filter with PL-259 to SO-239 Connectors Compact HF Radio Noise Suppressor and Interference Eliminator

The Comet TRF-MINI HF/6m RFI Choke is a high-quality solution for reducing or eliminating unwanted RF noise in amateur radio setups. Designed for operators who experience interference from modern electronics such as computers, LED lights, routers, or switching power supplies, the TRF-MINI helps ensure a cleaner, quieter receive signal. Its compact, 7-inch inline configuration with standard PL-259 to SO-239 connectors allows for quick installation at the antenna tuner output, feed point, or anywhere along the coaxial feedline where interference is present. Covering frequencies from 1 MHz to 55 MHz, it effectively suppresses common-mode noise on HF and 6-meter bands (80, 40, 20, 15, 10, and 6 meters). Built with a 50-ohm impedance and a 350-watt power rating, this RFI choke is both durable and efficient, providing superior signal clarity without signal loss. Perfect for home, mobile, or field operations, the Comet TRF-MINI ensures improved receive performance and enhanced overall operating conditions for serious amateur radio enthusiasts.
