    This program predicts approximate performance of general purpose,
    multiband, horizontal loop antennas of given perimeter of loop. It is
    not intended for precision predictions of operating data.

    A loop is a continuous wire without loading coil or capacitor. It can
    be of any shape provided the area enclosed by the loop is not less
    than 2/3rds of that of a circle of the same perimeter, ie., it is not
    too irregular.

    It is the sort of antenna which is forced on the amateur by the shape
    of his back garden and the pre-determined location of trees, poles,
    buildings or anything else from which an antenna wire can be
    suspended.

    Analysis includes a high or low impedance feedline, a choke balun and
    an L-tuner. The antenna is most efficient when the perimeter is a
    whole number of wavelengths. It is least efficient when the perimeter
    is an odd-number of 1/2-wavelengths. But operation is not limited to
    being at, or near to, resonant frequencies.
