high swr

Hi i have a question to ask about my cb. OK i have a cobra 29lx and every time i key up the mic i get a CB antenna warning that flashes at me. now im running the 29 lx, k40 mirror mount, Wilson 2000 antenna, and k40 18' copper coax. I have tried tuning the antenna with the meter on the radio and got channel one down from a high 3 swr reading down to a 1 but channel 40 is at 2 swr and still flashing CB antenna warning. i know that if channel 40 is high i need to lower the antenna so i took the whip out and cut of an 1/8 of an inch and still the swr is reading at 2 for channel 40. when i was using my old setup two firesticks and the coax that came with the 2013 386 everything was reading a high 3 swr i changed it all out and its gotten a little better but how do i go about getting channel 40 and 19 down to a 1 swr instead of it being a 2 and flashing the CB antenna warning at me? oh yeah and the coax is a 95% shielding which i heard is the ground for the antenna don't know if that is true but that's what i heard. I would also like to try and do this all myself so i don't have to waste time sitting at a CB shop when i could be running and making money. please any help or tips would be greatly appreciate thank you in advance.
