Do you need a counterpoise for your EFHW antenna? This video breaks down the fundamental electronics, including Kirchhoff's laws, to clarify how current actually flows in an EFHW antenna setup. Understanding these principles is essential for anyone trying to optimize their station and ensure their signal is radiating efficiently.
We also look at how to effectively use a common-mode choke to manage current flow. By adding a dedicated counterpoise, you can significantly improve antenna performance and resolve common RF interference issues. This technical walkthrough is designed for amateur radio enthusiasts who want to move beyond hearsay and understand the physics behind their equipment.
Subscribe for more antenna theory breakdowns, and let me know in the comments if you run your EFHW with or without a counterpoise.
