At our Contest Station ED1R, we have on each highband 3 Yagis available. In 2012 I built 4 high-power Stackmatches to switch and combine them properly. Since I never liked the way of WX0B’s stackmatch controllers with the rotative knob, a microcontroller and button-based solution were the answer. After a few contests, the solution has proven its reliability and comfort.
One of last year’s projects was the improvement of our Contest Station ED1R. For the various Yagis, we needed smart ways to combine antennas. Instead of buying commercial stackmatches (antenna combiners), I decided to build them up by myself and adjust them to our needs.
