1. A wearable electric field detector configured to detect an electric field generated by a high-voltage electric source in an environment, the detector comprising:
a first and second antenna;
an electrical circuit board operatively coupled to the first antenna and the second antenna, wherein the first and second antennas are mounted perpendicular to the electrical circuit board;
a power source operatively coupled to the electrical circuit board;
a plurality of indicators operatively coupled to the electrical circuit board and configured to provide an alert to the user indicative of a strength of a detected electric field;
an enclosure configured to house the first antenna, the second antenna, the electrical circuit board, the power source, and the indicators;
wherein:
the enclosure is configured to be worn by the user in a vertical orientation, a horizontal orientation, or in an orientation disposed between the vertical orientation and the horizontal orientation; and
the first antenna and the second antenna are spaced apart toward opposite sides of the electrical circuit board, wherein metallic pad portions are disposed on a peripheral forward edge of the electrical circuit board adjacent the first antenna and the second antenna, respectively, to increase sensitivity of the antennas and that the metallic pad portions are disposed proximal one of the antennas or both of the antennas and are formed as part of a metal trace structure of the electrical circuit board.
