Before watching this video, where did you think the return current came from?<br><br>The counterpoise?<br>The coax shield?<br>The ground?<br>Or were you never quite sure?<br><br>👇 Tell us below.

Since the EFHW feedpoint impedance is very high, the return current is relatively small. In many installations the capacitance of the coax shield to ground is sufficient to provide that return path. The downside is that the coax then becomes part of the antenna system, so moving or rerouting it can change the antenna's impedance, SWR, and radiation pattern.

Well explained video as i was using the efhw antenna unknowingly as long as the swr was perfect for me
