Good quality item that works great! I have 2 of them (base radio install and car radio install) and both are brilliant with very little loss and great interference rejection (rx not affected when tx'ing opposite band). I'd recommend to anyone needing to seperate antennas or combine sets to a dual band antenna.

I have swept the duplexer with professional grade test equipment and found the performance to be excellent. Insertion loss on each port was 0.2dB. Isolation notches were -70dB. Isolation port to port was better than -80dB. In all a very good unit with excellent performance with a 300W rating.
