Option 3 - dual antenna without a duplexer
In this configuration, antenna redundancy is supported with dual antennas connected to the Aprisa SR+
Protected Station TX/ANT (A/B side) and TX/ANT (B side) TNC ports on the front panel. In this option, the
Protected Station can operate in:
• Half duplex RF operation only
If single frequency used, standby radio RX (TX is off) can’t be monitored as it will receive the active TX.
If dual frequency used, and the ‘Protection Type’ is set to ‘monitored hot standby’ (Terminal > Operating
Mode), the standby radio RX/TX can be fault monitored. This mode has a 1 dB loss in RX sensitivity.
If dual frequency used, and the ‘Protection Type’ is set to ‘redundant’, the standby radio RX/TX will not be
fault monitored.
Option 4 - dual antenna with dual duplexers
In this configuration, antenna redundancy is supported with dual antennas connected via dual duplexers to
the Aprisa SR+ Protected Station TX/ANT and RX (A/B side) TNC ports and TX/ANT and RX (B side) TNC ports
on the front panel. In this option, the Protected Station can operate in:
• Half or full duplex RF operation
• Only dual frequency
When the ‘Protection Type’ is set to ‘monitored hot standby’ (Terminal > Operating Mode), the standby
radio RX/TX can be fault monitored. This mode has a 1 dB loss in RX sensitivity.
When the ‘Protection Type’ is set to ‘redundant’, the standby radio RX/TX will not be fault monitored.
