B&K 2040 CB Signal Generator
Old but very nice. Team it up with a B&K 1040 CB Servicemaster and you've got a great combination for testing and aligning CB radios. Yes you can get some nice shiny new equipment to service CBs, but the B&K items are specifically designed for CBs and do everything you need. Costs less, plus you can actually fix them yourself if they break. Try that with the latest Agilent gear!
