Antenna modeling for beginners, elevated radials (part 4).

- March 19, 2026

In this video, Callum (M0MCX) makes a strong case for using elevated radials with your vertical antennas.

Elevated radials improve ground conductivity and antenna efficiency, reduce ground losses, and enhance radiation patterns.

An elevated radial system uses fewer wires than traditional on ground arrangements.

Here are some comments from Callum (M0MCX):

In this episode we take the ground mounted vertical from Part 3 and add elevated radials to see how the antenna behaves. Using MMANA-GAL, we model a simple vertical and experiment with different radial configurations to see how they affect the far-field radiation pattern. In this video we: • Start with a basic ground mounted vertical • Add two elevated radials • Compare radiation patterns using the Compare function • Add additional radials and experiment with geometry • Raise the antenna and slope the radials downward • Observe how the low-angle radiation changes The goal here isn’t deep theory - it’s learning how to draw the antenna and observe what happens when you change the geometry. You’ll also see how elevated radials can slightly improve low-angle radiation, which is important for DX performance. In the next episode we’ll move on from verticals and start looking at loop antennas.
