There seems to be a rule of thumb for the dimensions:
Loop Diameters [cm] = Wavelength [m]
(e.g. 30cm loop diameter for a 10MHz loop) :-))
For more information on materials and dimensions, please use the label "shielded" down below.
|The loops for 30m and 40m.|
|The gap in the shield, opposite the capacitor.|
|The capacitor and coupling "box".|
