    A loop antenna crystal radio is of interest, on account of its portability, though it is no match for a crystal radio using an external vertical wire antenna and earth.

    If it's performance could be considerably improved with increased loop size, then its portability would be the first casualty.

    As usual, 2 configurations are possible - parallel-tuned-series-fed and series-tuned-shunt-fed.

    1. Parallel-tuned-series-fed version
