Good point 'Doc. I have never been able to convince anybody to try and tune the harness by trimming, the old fashion way. We did it that way back in the late 70 so we didn't have to know what the VF was so we could do the math trick. Trimming was a way to let the tune deal with this factor and get results. We did not get flat matches like everyone wants today. We stopped when we got a solid 1.5 or 1.9 SWR match and they worked pretty good with 75 ohm an 100 ohm if you could find it. Sometime we even ended up just barely reaching from side to side with the harness on some pickup truck rear bumper were we ran 102" whips.
