Greetings! What happens at my job, is I drive commercial trucks that has a cb antenna built in. I'm not always in the same truck day to day. Even during mid-day, I may have to swap trucks. What I'd like is some advice on using an autotuner that can match the 11m antenna to 2m/440 so I can plug in and go. A mag mount on top of the cab isn't much of an option because the top of the cab isn't as high as the fiber glass cargo box behind me. These are 36 to 42 ft freightliner and kenworth straight box trucks I'm working with. Any suggestions?
