    i bought my cb radio a year ago and got a company truck that had hookups for it that were not messed up and mangled.
    i can hear just fine with it about 2 miles range with these 1.5 foot antennas that came with the truck when i got it.
    planning on getting new ones soon but am wondering. Why when i key up the mic is the ant. light coming on? I know it means theres no antenna but its all hooked up properly. Could this be caused by using too crappy of an antenna or them being to short and underpowered? They are the ones swift used in 2010 so dont know if the previous driver damaged em somehow when they had the truck b4 me any help would be great and if its a problem with wiring i can get it to the body shop and have them correct it while i go on hometime.

    Most likely a high SWR reading. Don't key it up (talk on it) till you can get your SWR checked/set.

    1.5 ft antennas are not very good for CB. Get at least a 4ft antenna. 5ft is still better. And like Mike said check the SWR.

    If antennas are not connected he sure would not be hearing 2 miles away. I'm certain that it's a poor antenna system. Antenna, Coax, Ground, or All!

    if you get a strong enough signal you can hear some one talking about two miles away.the radio uses the coax,as it is part of the antenna system,for an antenna. the coax is connected to the radio,if you look out your window you can see the antennas mounted to the brackets but you can not see if the coax is connected to the antennas especially if they are the hidden type brackets as they are on most trucks supplied with antennas.
