I deployed a directional RX array consisting of a broadside-phased pair of 220m Beverages, 120m spaced, beaming toward North America (320°), a 200m Beverage on Ground (BoG) targeting Japan (44°), and a 60m BoG directed toward Southeast Asia (91°). These were connected to two Redpitaya receivers running Skimmer Server and an SDR-IQ with CW Skimmer, with all spots filtered through SkimCon software to eliminate duplicate spots before RBN submission (3V/KF5EYY node). SkimCon preseves a raw data log with skimmer number associated to each spot, for analysis. Subsequent data processing by Excel and VBA produced a radar plot that clearly visualizes each antenna's dominant contribution in its intended beam heading, along with the identifiable effects of its side and rear lobes, providing a real-life quantitative assessment of their directional performance. I was impressed by the performance of the Broadside Phased beverages. In multiple occasions, I was the only station outside North America that spotted US stations.
