Satellite Antenna Redundancy

One common setup comprising six Ku-band antennas, each with four L-band signals (Horizontal High, Horizontal Low, Vertical High, Vertical Low) is backed up by one redundant antenna. This arrangement called “4*6+1” protects six primary signal paths using a single redundancy antenna path (6+1). Four of these channel redundancy units, one for each polarization (4*), are configured within a single switch DEV has developed a single switch to handle all of these features. Up to four redundancy units each serving 16 signal channels are possible (4*16+1). The DEV 1993 is specified for frequencies up to 2.45 GHz and is available in 50 ? with SMA connectors or in 75 ? with precision F connectors. High isolation separating the distinct service channels from the redundancy channel is attained to ensure optimal signal quality. Local setup and control for the device is implemented by a web interface for configuring, switching and monitoring the device This product can also be expanded to set up and steer a motorized backup antenna via controller to create an operator free backup system switching signals from any failed antenna to the spare path.
