Hello Stefan,<= /div>
 
probably you already know, th= e ultralightdx group on yahoo contains many references to a so-called Ferri= te Sleeve Loop antenna (FSL) to be used for LW and NDB DXing with tiny (ult= ralight) receivers. Could it be of some interest for you?
= Also found this link about the FSL antenna concept: http://www.gmweb2.net/The%20FS%20Loop.= htm
