I honestly can't say that I ever claimed a 1/4 wave antenna would -always- show an input impedance of 35 ohms. I have said that an input impedance for them averaged between something like 20 and 40 ohms. You have to admit that 35 ohms falls in that range. Can anyone predict what a typical 1/4 wave mobile antenna's input impedance will be? No, not me or you or that other guy over there. We can all be pretty sure that it will fall in that range of impedance though (20 - 40 ohms).
So, I'm going to take your advice and ignore your posts. You may have learned to operate EZNEC, but I don't think you understand what it's telling you yet.
