WebFigure 2. Direction finding antenna schematic. Resonant Loop The tricky part is finding a compromise loop diameter (wire length) that will cover the desired frequency range with reasonable capacitor values. This takes some experimentation. I ended up with 73 inches of 14 ga magnet wire (any insulated wire is fine), wound into a two-turn loop.
