After reading a number of articles by the late Walter Maxwell W2DU ARRL technical adviser, I was prompted to carry out some of my own experiments with mismatched loads. I carried out a couple of similar experiments that Walter described in chapter 19A of his book “Reflections”. My experiments were not as comprehensive as those […]

What does your SWR meter tell you?
Probably the first question that should be asked is, what is SWR? Simply put, SWR is the ratio of the maximum voltage (resulting from the interaction of incident and reflected voltages along a transmission line)to the minimum voltage. In a correctly terminated line (that is where the load is equal to the characteristic impedance of […]
More of my reflections on Standing Waves
More of my Reflections on Standing Waves Fact and Fiction Over the years much misleading information has been published regarding the behavior of antennas that are not self-resonant and also feed-line performance in the presence of standing waves when mismatched at the antenna. The readings given by our SWR meter are often not well understood. […]
