Shielded Loop (some photographs)

No new development yet. Here are some photographs to help the imagination. The loops will be provided with some amplifiers soon-ish.

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".
