cb getting no signal???
i have this cb mounted in my truck
http://www.amazon.com/gp/product/B00...Fencoding=UTF8
i have one of those antennas that goes through the window on it and it gets no signal. i had one wired through the back and it didnt help either. do you know what the problem could be
it turns on but seems like it gets no signal.
thanks guys
ps i work for a trucking company, that is why i have it.

The factory tint doesn't. I have a VHF antenna coupled that way and it works fine.
Most likely, if you can't get it to work with EITHER antenna: then your coax is bad or your radio is bad. Try another piece of coax.
Thru-window antenna's never work well at CB frequencies. Just not enough capacitance through the thick glass to couple them well. At higher frequencies they can work quite nicely. I agree that you should dump that and stay with a whip.
Also, many CB's (like Cobra's for instance) are wired so that if the microphone is not plugged in, they don't even receive. You could have a bad mic cable or connection in the connector that is keeping the CB from going into receive mode. So that's another potential problem.

I was just thinking, do you even have a mic for it? does it take one? I know of someone on here that had his set up and told me it didnt work and it was because he didnt have a mic hooked up to it. Lol

First of all, you need to remove the splitter and that crapola. That is probably half the problem right there. Unfortuantely, you can't just split antenna feedline like that.
Second, as Master Griggs pointed out, a jelly donut with the coax shoved in it will radiate better than a glass mount CB antenna. Might as well ditch that too.
Start fresh with a real antenna either magented to the roof or bolted to the back of the cab. I bet you'll see an improvement.

I forgot he had that crazy cable hooked up. An unterminated 1/4 wave stub can do all kinds of nasty stuff. I agree with Matt -- get a different cable first thing.
