In this video, I measured some key parameters of a C-1205-20 directional coupler from Werbel Microwave and did a few experiments demonstrating its use as a power combiner and as a reflectometer for antenna SWR measurements. Sorry no teardown in this video as Werbel Microwave requested me not to teardown this one due to some proprietary designs.
