Decibel db-4056 vhf repeater duplexer ~nice condition~
The DB4056 duplexer is designed for use with a single, broad band antenna in a mobile repeater or duplex-type system. This model operates in the 150 to 162 MHz band when the transmitter and receiver frequencies are separated by 2 to 5 MHz or more. Six sealed quarter-wave helical resonators are interconnected in a band-reject configuration with double-shielded coaxial cable to provide 75 dB rejection (nominal) to transmitter noise and 75 dB isolation(nominal) to receiver desensitization.
A .pdf copy of the DB4056 installation and tuning instructions are available upon request.
Includes mounting brackets for installation in a standard 19" equipment rack.
