The airport-friendly 3.5 inch "Frequent Flyer" FSL antenna was specifically designed for easy, hassle-free airline travel to exotic places around the world. Despite the fact that it fits easily within hand-carry luggage, it can provide inductive gain boosts comparable to those of a 4 foot air core box loop (once the DXer becomes skillful in its operation).

This morning one of these "Baby FSL" models demonstrated exactly what it can do to enhance transoceanic signals at the Rockwork 4 ocean cliff near Manzanita, Oregon. During typical propagation it provided tuned gain boosts to a stock C.Crane Skywave model, resulting in these enhanced transoceanic signals from New Zealand and Australia.
