A heavy 2 m x 2 m floor-standing wooden showcase in the shack appeared to be suitable as a frame for a crystal radio loop antenna. As luck would have it, the lone 20 km distant 612 kHz, 200 kW AM broadcast station being in the end-on position by default, there would be no need to move the unit. The counter top would make it quite convenient to sit down and carry out the testing.
The 5 turn loop was easily wound using about 42 m of ordinary hook-up wire.
The shack is relatively quite small to get a photo of the actual unit.
Here's a representation of the same.

It works quite well with my series/parallel-tuned crystal radios.
