The GRC-408E is the latest generation of the high-capacity, line-of-sight /HCLoS) broadband radio relay system.

The software-defined radio relay systems supports the latest IP and legacy communication protocols. It is ECCM-capable, enabling interference-free communication.

The GRX-408 is capable of multi-mode, high speed data transmission (100Mbit/s per link in band IV).High sensitivity, combined with its robust modulation schemes, provides very high link availability. The GRX-408 is field-proven and in operation with numerous armed forces around the world.
