- I have what I think is a significant discrepancy between my model and reality, I would be interested if anyone on the list might be able to offer any insight or explanation. The antenna is a custom T

- Dave, First, take the 10 ohm 'ground loss' resistance out of the model. 48 radials approximately 1/4-wavelength is a low-loss ground. Without it, the 'zero-X' spot is around 36.5 ohms at 3.840 in my

- Second what Gary said. Further, from my experience in model vs. actual, the one thing I *don't* worry about is the exact presented impedance. The model will tell you things to try, things to avoid, b

- Doesn't it seem strange that your antenna never actually resonates (X=0)? For a simple quarter wave vertical, you'd expect that if you went high or low enough in frequency, the reactance would go thr
