Be careful here. I was close to 1:1 SWR on low channels and about 1:4 on higher channels. I want it to be better. I worked at and now I at about 1:4 on lower and 1:6 on higher channels. I decided to quit while I was ahead and live with it. They say anything below 2.0 is fine. I was playing around with a magnetic antenna I could put it on the cowl and be just under 2.0 and moving an inch to the hood was closer to 3.0. Even opening and closing doors changes the SWR on my jeep.
