I'm relatively new to the scanner and amateur radio scene(working on getting my tech license), but have been interested in them since i got my first CB about 3 years ago. But my question is: is it possible and or practical to use just one antenna for both of these purposes. With the scanner i would want to be able to cover as many bands as possible. or would it just be easier to just have 2 permanent NMO mounts in the roof and just swap out scanner antennas as needed while leaving the 2M/70CM band antenna?
