         The rule given in (eg Antenna Engineer's Handbook
         Jasik, others) is that radials should be about
         1/4 wave long, which is roughly the tower height in
         many cases.  The same maybe observed in CB and
         scanner antennas...

>>I can't see why this shouldn't be at least as applicable to TC's.

         Broadcast practice is designed for radiation.
         Tesla Coils commonly are not.

         And a 1/4 Wave at (say) 150 KHz is 'interesting'.
