Portable Faraday box is intended for taking measures on checking the radio equipment EPIRB without emanation in ether without any influence on the precision of measuring.
Portable faraday box is a kind of metallic box with radio absorbent covering inside, repeatedly decreasing internal reflection. This allows to give a signal without distraction from tested radioequipment to installed beyond the camera a diagnostics device and controlling equipment.
The receiving antenna with cutoff point allows to give a checking signal on tester.
Portable Faraday box
-allows to check operation factors of EPIRB in operational mode the transmission of a distress signal to sattelite :
-combined with EPIRB tester
-eliminates influence of surrounding radio signals and noise for proper check of EPIRB
External dimensions 450x430x850(mm)
Aperture for placing EPIRB in camera
Weakening of a signal 40 dB
121,5 MHz and 406 MHz
