Turning a Cellwave duplexer for a GMRS Repeater

In this video, I’m using the Anritsu spectrum master MS2721B for setting up a flat pack cell wave duplexer that will be used on a friend of mine‘s GMRS repeater In this process, I explain certain aspects of calibration high pass and low pass notch alignment to achieve and acceptable, noting characteristic, as well as maintaining a minimal return loss on the pass bands When performing these processes, it mostly just takes patience and a test instrument that is able to perform with a low noise floor, preferably around or below -100 DBM unfortunately the VNA products although very useful generally don’t perform well with these particular tasks Hope you enjoy the video like share and subscribe
