looking for information as to what this is as well as if it has any value

 

We need more information. Take pictures. Provide a model number. Clue us in on what frequencies it's tuned for. A duplexer, to way-oversimplify, is a "filtering" device that, among other uses, allows repeaters to function using a single antenna for transmitting and receiving. They can be fairly valuable.

some are junk, some are failry decent. Really depends what you got..  Freq range??  Does is spec (notch) for the tuned frequency?..  They are older duplexers but if they bench out well i wouldn't throw it away..
