Walk or drive around with this handheld, directional noise finder with 3 element beam and meter to search out foxes, leaky insulators, loose hardware and corroded ground lines quickly. Track the noise source right down to the pole, transformer, or insulator, or other source. Operates in the 135MHz region where activity is a minimum and radiation from corona and arcing is far more localized. 0.3 uV sensitivity and wide-range AGC for noise level meter.
