Re: rf feild detector

I suggest a wire antenna followed by several cascadable amplifier modules and then a diode detector and then an op amp stage and then an analog meter or a comparator.

rf feild detector

Depending on the existing RF enviroment (e.g. presence of mobile phones, wireless LAN and other wireless operated
equipment), a non-selective wideband detector may be more or less useless for the said task. In this case, you won't come
far without a portable spectrum analyzer, e.g. a TTI PSA2701.
