Spiral Antenna
UHF Spiral antenna is a partial discharge sensor designed to receive electromagnetic (EM) emissions from a PD occurring in the monitored asset. It is a broadband antenna with a flat response which makes Spiral antenna suitable in a number of different applications. It has been optimized to operate in a frequency range typical for PD activity and it was designed to provide maximum sensitivity and high gain.
