FS: TXRX repeater duplexer 28-70-02: I have for sale this nice repeater duplexer. Tunes into ham band with no problems. $375
The TX RX 28-70-02 is a Vari-Notch® Duplexer designed for 450-470 MHz frequencies with a 5 MHz split, capable of handling up to 350 watts of transmit power.

Split: 5 MHz.
Power Handling: 350 watts.
Circuit Type: Vari-Notch (also referred to as pseudo-bandpass), which offers a combination of series-tuned and parallel-tuned circuits, providing a deeper notch than series-notch designs.
