Full Duplex Hot Standby Base Radio
QH450 - Hot Standby Full Duplex Radio
Complimenting the QR450 half duplex remote radio, the QH450 full duplex radio kit is ideal for deployment at base & repeater
sites in systems using two frequency operation. In high duty cycle applications, the QH450 delivers maximum rated transmitter
power in ambient temperatures up to +70°C (158°F). Where 1+1 hot standby redundancy is not required,
the full duplex QB450 base/repeater station is available.
The features of the QH450 include:
• Full Duplex operation (100% duty cycle)
• Ethernet link monitoring and shared IP address
provides smart Ethernet redundancy
• Remote monitoring, control and changeover of
duplicated base/repeater stations
• Hot-swappable modular 19” rack mount
transceiver configuration (3 RU total)
• Automatic changeover upon alarm detection of
transmitter, receiver, data alarm detection, power
supply and data connectivity.
• Digital Inputs & Outputs
• Hot Standby Controller power supply
• 11-14V DC (from output of QBs)
• Max Current: 800mA
