So have you installed the cb and antenna yet? If you ran power from the battery and did not loop up your excess antenna cable; I believe you will be just fine. I have a cb antenna tuner, only been used once (when I put a cb in the 40) and you are welcome to use it to tune your radio. The actual tuning process is pretty straight forward and only takes a few minutes if the installation was "clean".
