Portable QRP HF Common-Mode 20m and 40m Choke for TX-500 & TX-500MP | Compatible with Any HF Radio Using N-Type Connectors

This portable HF common-mode choke is designed for the TX-500 and TX-500MP and is compatible with any HF radio using N-type connectors. Intended for installation at the radio feed point, it helps suppress common-mode current on the outside of the feedline and may also be installed elsewhere in the feedline where common-mode suppression is needed. Measured performance provides over 750 Ω of common-mode impedance at both 7 MHz (40 meters) and 14 MHz (20 meters), with a maximum measured impedance of 950 Ω at 10.5 MHz. Its compact, lightweight inline design makes it well suited for portable HF operation.
