Tuning a CB with magnet mount antenna

[PeteC]

Hey guys. So I'm using a Midland 75-822 with a Wilson Little Wil. I initially set it up with a SWR meter and got good readings across all channels with minor adjustments. My question is, being that it is a magnet mounted antenna, if it moves to a slightly different part of my 4Runner, will I need to re-tune it? Thanks for the help

Probably not. It's the length of the antenna and the ground that's dictating the SWR. Even if it is moving, it's only a fraction of an inch unless you're literally knocking it off the top. I should probably test mine though (I have the same antenna) and see where it's at compared to when I originally set it because I'm always bouncing it off branches and drive through signs. I've also actually knocked it over to go through a parking structure once so it isn't in the same spot as when I originally set it up.
