i just got a cobra CB that was taken out of a semi truck at work, it worked in the truck, but was removed because one of the dials didnt light up anymore so they just replaced it. i put it in my jeep along with a magnetic antena that i attched to my smittybilt tire carrier, the last time the antena was used it worked. well i dont get anything out of it, i adjusted the squelch knob and still didnt hear anything, but when i walked over to a truck people were talking constantly on the same channel, i have another magnetic antena but its a big whip one and i dont really want to hang that from the top of my tire carrier, at work we have the ones that go on the semi truck mirrors, and i saw some jeep place had a bracket for that kind that attches to one of the tail lights, but i cant find it anymore, anyone have any suggestions on how to set it up to so i can hear people and get the best range possible?

theres a few posts on here that explain what to do. i belive you need a meter that reads your signal or some such, also the antenna might screw in or out to help boost your range. the type of cable you use, and where you get your power frlom are also factors in the sound quality. im not sure why your not getting anything. does the cb light up and turn on? bad ground??? i hope any of this helps. look around for more posts i belive theres a few. good luck

Use the length of cable needed to make the connection with enough slack to allow easy cable routing, and no more or no less.
Another that could be confusing is where they say antenna cables need to have a "50" Ohm impedence which is incorrect, the correct impedence for a CB, its antenna, and its cable is technically 52 Ohms. Some might be searching for 50 Ohm cables if they didn't know better.
Most of their information is correct but take it with a grain of salt.The Geezer Jeep: http://www.greentractortalk.com/jerryb/index.htm

yea thanks guys i found one at a local electronics store, its a cobra highgear M75, it looks to be pretty nice, the radio is from 1998, it was in a semi at work and they took it out to because some of it doesnt light up anymore, so i took it because being a student im too poor to afford a decent one.
