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...

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

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