Video looking at an initial idea for a directional coupler. Please note that this is not suppose to be a competition or commercial grade device. My aim is to keep the costs down, but still have a functional power/SWR meter at the end. The aim now is to condition the DC before feeding it into the Arduino.
I did not mention in the video that I placed the directional coupler between the antenna tuner and the dummy load. I did not see any increase in the tuner's SWR meter as a result of the directional coupler.
