2.8 inch (71mm) Micro FSL Antenna Demo Video
Since its modern introduction 10 years ago the Ferrite Sleeve Loop antenna has provided a compact AM-DXing breakthrough for portable and traveling listeners, and was directly related to the "discovery" of the Rockwork and other ocean side DXing cliffs in Oregon state.
The "compact DXing breakthrough" aspect was emphasized in the development of the all-new 2.8 inch (71mm) Micro FSL antenna, which is the smallest and lightest high-performance FSL ever developed here. Using Amidon 3/8" x 4" ferrite rods instead of Russian surplus ferrite, the Micro FSL weighs in at 1 pound 13 ounces (.82 kg), and can fit in a large coat pocket. Despite this compact size the antenna is a tiny firecracker for AM-DXing gain, as demonstrated in the YouTube video at the following link.

Since all of the construction parts for the 2.8" Micro FSL are readily available here in the USA, the airport-friendly antenna should provide a great new option for traveling DXers looking for a huge gain boost in exotic locations overseas.
