Like Booyah already hit on, you can't just hook up any old antenna. That goes for everything, not just CBs. All antennas are designed to work only within a given frequency range. Not only is that antenna almost certainly not a match for 11m (which is the wavelength of CB comms), it's probably WAY off. Getting it to work for CB applications shouldn't even be considered. If you do attempt to use it, on receive you'll get extremely poor performance, and on transmit you could literally damage your transceiver (unless the excessive SWR causes protective circuitry it may or may not have to shut it down before damage does occur which would be best case).
Don't use anything other than a CB-specific antenna (50 ohms impedence).
Also, like EWO said, coax impedence is a consideration. Anything made for mobile radio is going to be 50 ohms, & that's what you want. 75 ohms is cable TV, & that's what you don't. 11m generates very little coax loss, so you don't have to get fancy. RG58 is what I'd recommend, unless you're looking to upgrade sometime in the future to a ham license, in which case rg-8x would is still real easy to run & would do better at VHF/UHF frequencies.
