1. An RF detector for detecting RF signals, comprising:

  • a gain circuit for amplifying the RF signals;

    a rectification circuit for changing the RF signals to a DC voltage;

    a comparator for comparing the DC voltage to a reference voltage; and

    an LED coupled to the comparator for indicating that RF signals are present within the RF detector and for indicating that RF signals are not present within the RF detector, wherein RF signals are present when the comparator detects a difference between the DC voltage and the reference voltage
