Many thanks to SWLing Post contributor, Gary DeBock, who shares a video of his latest Ferrite Sleeve Loop (FSL) antenna: the 3″ Baby FSL.
The new design 3 Inch (76mm) Baby FSL antenna is the smallest, most compact and lightweight of the “airport friendly” FSL’s developed here recently, but it provides a very potent inductive coupling boost for weak AM-DX signals.
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!

Great video showing impressive performance. Does this work equally well throughout the AM Band? Where can you buy this? Do you publish instructions on how we can make our own?
Love the small portable design, can carry it anywhere. But it needs a handle on top to make that easier. I wonder how this compares to the performance of the C.Crane Twin Coil Ferrite antenna? This needs a shootout! The new variable cap and wire seem to be working very well!
