Features and Benefits
High performance window filter duplexers for the
700 MHz band (Fixed Base/Repeater Frequencies) enhance receive selectivity, isolate
transmitter and receiver to prevent interference from transmitters, and enable simultaneous
transmit and receive operation using a single antenna. TX-RX isolation is established by the
duplexer, not by spacing of two separate antennas.

Designed for multiple-frequency operation
Milled aluminum construction provides outstanding selectivity characteristics in a rugged and compact
package – only 2 RU high

This was used with high-power Motorola Astro GTR 8000/ gcp 8000 Repeaters.
