2.3.8 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.
