I actually have a question about this topic.i have calculated a few different center frequencies (10m,6m,2m&70cm) using no more than an swr meter .the material i used in all cases was steel whips from old junk cb(11m) antennas.where the standard formula is (for a quarter wave) is 234/freq. ,i instead came up with 238.5/freq. try it,and give me,and everyone else your feedback. 73,kc5lur
