The appropriate form for the surface impedance of a radial‐wire ground screen is utilized to obtain quantitative effects of the important parameters (number of radials, length of radials, wire radius, and ground constants) on the low‐angle radiation of a vertical antenna. An approximate correction term is derived to account for currents reflected from the edge of the screen. The effect is small for large screens, but it may be important for smaller screens.
