RFI Industries has released the IABF9216 isotropic broadband field probe manufactured by Schwarzbeck Mess-Elektronik. It is an active three-dimensional monopole antenna designed for performing E- field measurements in three orthogonal directions.
It covers the 9kHz to 3GHz frequency range and, when used in conjunction with a test receiver or spectrum analyser it is able to perform frequency selective measurements.
The antenna factor is constant over the specified frequency range at 44dB/m to 53dB/m.
Measurements of field strengths in the range of 0.1mV/m to 30V/m are possible, with a maximum isotropic deviation of under 2dB. An optional weather-proof housing is available to allow external mounting of the antenna for long-term data collection.
