I'm working with some old software to optimize antenna networks, and I've come across some stuff that I don't understand. For the software to run, all impedence values entered must be normalized to 1 ohm. What does it mean to normalize an impedence and how do I do it? Also, the manual for the software keeps referring to a Yarman geometric norm when it talks about normalizing these impedences. What is a Yarman geometric norm? I apologize if I sound daft. Any help would be much appreciated!
