Antenna gain

I would have figured the lower the db the longer the whip just to help with extended range?
To give a simplified answer to your question, higher gain antenna's are generally longer to provide more phased elements in the antenna's. The number of phased elements is what provides the gain by compressing the radiating lobes. Don't get too hung up on antenna gain as gain provided by cb antenna manufactures is sometimes at best a guess or a theoretical gain which is seldom achieved in a vehicle installation.
