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.
