Many thanks to SWling Post contributor, Gary DeBock<\/a>, who shares the following note about his latest FSL antenna experiment:<\/p>\n

Medium wave DX FSL antenna phasing experiment– 1593-CNR1 (Changzhou, China, in Mandarin) boosted up to strong (S9) peaks by two 5 inch “Frequent Flyer” FSL’s at 1435 UTC on February 25th in my frozen back yard in Puyallup.<\/p>\n

Unlike other high gain MW antennas, the FSL’s can provide cumulative gain at very close inductive coupling ranges.<\/p><\/blockquote>\nhttp:\/\/swling.com\/blog\/wp-content\/uploads\/2017\/03\/1593-CNR1-1435z022517CCSW.mp3<\/a><\/audio>\n
