Theory of Elevated Radial Systems for Vertical Antennas

Date: 2026-01-13

• Elevated Radial Systems for Vertical Antennas behavior depends on electrical length, height, and nearby objects.
• Current distribution drives the radiation pattern and feed impedance.
• Ground conductivity and mounting height affect take-off angle and efficiency.
• Feed line and support materials can introduce detuning.
• Modeling improves accuracy over closed-form estimates.
