All RF Shamans Ltd radio-scientific instruments utilize our in-house designed outdoor cabinet solution that has three layers of EMI/EMC/RFI protection. Not only do our software defined radio-scientific space weather instruments fulfill relevant EMC standard requirements, but exceed the conducted and radiated emission limits by many tens of decibels, rendering our equipment 100% radio silent. This makes possible instrument integration directly below our extremely sensitive radio receive antennas. These instrument cabinet solutions are designed for environmental extremes and so our instruments may be found providing service from Svalbard to Puerto Rico.
🇫🇮 All products designed and manufactured in Finland!
