Many thanks to SWLing Post contributor, Gary DeBock, who shares a video of his latest Ferrite Sleeve Loop (FSL) antenna: the 3″ Baby FSL.

This demonstration video shows its huge boost to a weak daytime DX signal from 1070-CFAX (10 kW in Victoria, BC, Canada) here in Puyallup, WA, USA:

Most impressive, Gary! You’re right: that design is compact enough that it should even fit the bill for my one-bag travel philosophy. I think I might have to build one of these!
