T2-2R with Duplexer and Triple Relay Option Kit

The CA01962AA T2-2R with a Duplexer and Triple Relay option kit adds the capability to dynamically
tune the TX frequency based on the active channel. The GTR 8000 Base Radio is a normal duplexed
repeater while the GPW 8000 Receiver monitors the TX frequency. The other channel is for talk-
around (transmit and receive). This option is sometimes called the triple relay option. A GPW 8000
Receiver is used to monitor the second frequency.
A standalone T7039A GTR 8000 Base Radio is required for this option kit. One GPW 8000 Receiver
must be ordered without this option. This option kit includes 3 RF (transmit/receive) antenna relays,
control cables, RF cables, and mounting hardware. The base radio must be ordered with the
appropriate duplexer option.
All option kit hardware and cables required are included in

NOTICE: The photos and illustrations in this section show the GPW 8000 Receiver with one
