RFDS - External Dual Circulator/Isolator Tray (700/800 MHz)
An option for the GTR 8000 Base Radio is an External Dual Circulator module which isolates the base
radio from the antenna, thus preventing the transmitter from generating intermodulation. The circulator
load dissipates reflected power. It includes a cable that connects to the RF Peripherals port on the
base radio backplane to provide temperature monitoring.

RFDS - External Dual Circulator/Isolator Tray (UHF)
An option for the GTR 8000 Base Radio is an External Dual Circulator module which isolates the base
radio from the antenna, thus preventing the transmitter from generating intermodulation. The circulator
load dissipates reflected power. It includes a cable that connects to the RF Peripherals port on the
