Manufacturer’s specs are located at https://www.dbspectra.com/products/143-156-mhz-duplexer-db4060-wc-b/
I bought this duplexer used about six years ago. It has been in environmentally controlled storage (my basement lab) since I bought it. The steel case is a bit roughed up with scratches. The inside of the case and the duplexer are in excellent shape. Electrically, it meets manufacturer’s specs. Pictures of the unit and test results using my HP8753C VNA at 147.04/64 MHz are shown below.
I am asking $600 for the unit. The price includes tuning to your frequencies. No shipping, pickup only. I live in Howell, Michigan (south east Michigan).
