Oliver Heaviside and the theory of transmission lines (2021) (pa3fwm.nl)
An antenna cable is not just a piece of wire. Technically, it's called a "transmission line", with special properties such as its characteristic impedance. But transmission lines are quite a bit older than radio technology: they date back to the second half of the 19th century, in the form of (mostly submarine) telegraph cables. In this article we look at the principles and properties of transmission lines, with special emphasis on Oliver Heaviside's contribution to our knowledge of them.
