Hi Mick,

Smith mentions using frequencies around 20MHz. The coil had no specific resonant frequency or it resonated at all frequencies. The wire was 20 feet long the ferrite tube was 8 inch to a foot long according to the description given in this letter: http://www.rexresearch.com/smith/smith2.htm#middleton http://www.rexresearch.com/smith/smith2.htm#middleton

Regards
Ole

 Ole,
 Does Smith give any clues as to what frequency he used the 25 feet would be about 40mhz fullwave?
