In this video, we explore the effect of counterpoise length when using EFHW antennas in amateur radio (ham radio) setups. Whether you're a portable operator, a QRP enthusiast, or setting up your first HF station, understanding how counterpoise length interacts with your EFHW antenna and whether it makes a difference in SWR, radiation efficiency, and signal strength.
