WebJan 24, 2024 · The extreme case of imbalance when feeding a half wave antenna occurs when it is fed from the end. The impedance at the end of the antenna will be quite high - typically 5,000 ohms or more. To tame this high impedance, an impedance transformer of at least 9:1 and as high as 49:1 is often used.

WebNov 13, 2012 · I’ve posted about end-fed, half-wave antennas before, but until this weekend, I’d never built one. One of the reasons for this is that most designs are for QRP antennas and not made to handle more than 5 – 10 W of power. A couple of months ago, I ran across a design rated at 100 W.The design seemed relatively simple to build, …
