Many thanks to SWLing Post<\/em> contributor, Markku (VA3MK), who notes that Swiss manufacturer Stampfl has introduced the MWS-1 Standing Wave Barrier.<\/p>\n

Stampfl notes (translated from German):<\/p>\n

A standing wave barrier can improve reception. The standing wave barrier interrupts the ground loop and suppresses the interference caused by the cable shield.<\/em><\/p>\n

This is designed only to work with receivers (not transmitters) between 0.15 – 30 MHz.<\/p>\n

I suppose this might be a form of an RF choke, although I’m sure someone else might know better.<\/p>\n

Thank you for the tip, Markku!<\/p>\n
