NVIS ANTENNA THEORY AND DESIGN
region6armymars.orglet’s look at the theory. Figure 4 shows a theoretical two-element yagi designed for 75m (3.8 MHz). The antenna consists of a half-wave dipole driven element and a passive reflector. The reflecting element is 5% longer than the driven element and is located 0.15 wavelengths behind the driven element. This is a very standard 2-element Yagi design.
