How to model a 6:1 ratio balun using NEC2
I am using Nec Win Plus (NEC2) to view the SWR curve of my modeled
antenna. The actual antenna uses a 6:1 ratio balun. Is it incorrect to just change the characteristic impedance of the line from 50 ohms to 300 ohms to see what effect a 6:1 balun would have on the SWR values? I was just assuming that the line impedance was only really needed to calcuate SWR - hopefully I am right. Thanks, Scott, WU2X |
