WebBecause the feed point impedance of an end fed half wave is high the current must be low. For 100W carried it's in the 0.25A or less range. For example 1600 Ohms x 0.25A 2 is 100W. 1600 Ohms would be on the low end for an end fed half wave. The current at the connection point to the unun won't be significantly higher.
