Smart radio:
Superior radio design for maximum performance
4RF has a long history of developing high performance radios, and the Aprisa SR builds on this same engineering excellence.
The Aprisa SR’s receiver maintains exceptional low noise operation via excellent sensitivity for greater distance and high selectivity and intermodulation suppression for superior protection from interference.
This performance is complemented by fast switching circuitry and high transmit power ensuring long distance operation with exceptional system reliability and availability.
