I have an old 2m log-yagi that I would like to model. The 5 driven
elements have a gap in the center. When modeling, do I use the
tip-to-tip distance or just the length of the tubing used? Is the
zigzag feed 100 ohms?

Hi Fred,

Model it exactly as it exists. Model the zig-zag too and it will sort
itself out.
