A low SWR is never anything to worry about. The lower the better. As you can see in the plot above, the low point should ideally be in the middle of the band. Channel 20 is the middle of the Citizen's band. All is as it should be.

ive owned dozens of mg mount antennas. the k30 was the worst
i liked the lil wil better performance wasnt much better but swr seemed
to be a tad better. if my memory is right.if you can use a longer antenna
the look at the wilson 500 @ 4ft [about] or wilson 1000 @5 ft [about]
the 500 surprised me it worked almost as good as the 1000 and was
shorter.the downfall is you cant remove the coil./whip .gotta remove whole antenna
on the 1000 you can remove the coil by unscrewing it keeping the mount /coax
in place.

Actually, the mismatch to be concerned about is the one between the feedline and the antenna itself. That's where "SWR" is really determined.

You're absolutely right, lousy wording on my part. What the meter sees has nothing to do with the radio technically, it's all about the feedline and the antenna. The radio just senses the mismatch, if there is one.
