CodeRunner 4 - HS

Microwave Radio Communications
Close Move

The CodeRunner 4 combines the features of a high performance analog and digital central receiver, capable of accepting COFDM, QPSK, or 16QAM modulation schemes.

Digital capability is added using the RXL-HS Integrated Receiver & Decoder. A media switch changes the receiver from analog to digital mode.

CodeRunner 4 provides seamless integration with MRC's AccuScan and TouchStar Antenna Control systems supporting a wide array of MRC's steerable, sectorized, and omnidirectional antennas.
