Web2 apr. 2024 · This isn’t particularly good for the low angles of radiation favored for DX, but it can make an excellent NVIS antenna for local contacts on the lower HF/MF bands (40m, 60m, 80m, and 160m) when operating below the critical frequency. The ground acts as a reflector, which improves signal strengths at some heights. WebThe correct antenna pattern, shown in Figure 1, is surprisingly easy to generate. First let’s look at the theory. Figure 4 shows a theoretical two-element yagi designed for 7 (3.8 … dualsense flashing blue
