📡 Does Counterpoise Length REALLY Matter for EFHW Antennas? Let's find out in this deep dive into End-Fed Half-Wave antenna (EFHW) and coax length performance!

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.

EFHW antennas are great for HF portable operation, POTA, SOTA, and field day setups.

🔧 This information is perfect for:
o HF ham radio beginners
o QRP operators
o POTA/SOTA/WWFF activators
o Anyone troubleshooting EFHW performance issues
