how do you ground the cb??? i did the tailgate ground but ive never heard of grounding the radio.

 

The black wire coming from the rear of the CB is the ground wire for the CB. I just grounded it to the body of my Jeep and it works well. I did not run the ground to the battery just because I did not want the battery clutter we see on so many rigs. The point is, a ground is a ground. Without this ground your CB will not work.

 

ok i thoguht there was another type of ground

 

Even when having the black ground wire to the chassis, it doesn't hurt to have the radio mounting bracket into some good metal as well. And then the bracket then grounded to the radio via the bolts holding the radio. I know this isn't always possible all the time on the JK having so much plastic and all, but it doesn't hurt to have another ground of some sort to the radio as well as the black wire to ground.

 

Back on Aug. 20th. you started a different thread about your SWR being high with the same setup. Through me off at first thinking this thread was a different member with the same rig and SWR issue. Keeping it in the same thread helps us help each other, anyway how did you fix your first SWR issue when your readings were through the roof. Was it a bad ground as you were thinking.

 

I'm not here to start an argument. That being said..... One ground is all you need. As far as the bracket goes, I was supplied with rubber washers to go between the radio and the bracket. So that part is out the window. All in all, as long as your radio has a ground it will work. As far as the antenna being grounded, well thats another story.

I hope no one takes an offense to my comments.

 

You will be already grounded twice anyway when you think about it as you are grounded from the black wire off the back of the radio, and as long as your antenna is grounded good enough you will also be grounded off the back of the back of the radio where your coax is connected so like you said you will have enough grounds, and so just make sure the antenna is grounded well.
Just my little .02 cents worth rounded off to a buck

Yup, it was a bad ground. I just ran a 10 gauge wire with some crimp connectors on both ends from the antenna mount and drilled a hole in the frame of the JK.

 

Nope....you are not grounded twice. Don't confuse DC ground with RF ground.....two separate entities. That's like saying if you hook your coax to the back of your radio your radio should power up. Or the other way around, if you hook up the black DC wire to ground, your antenna should work without the coax shield connected to the back of your radio. Yes....you only "need" one DC ground to make your radio turn on, but it doesn't hurt to have another radio ground. In fact some, (HAM radio ops with spendy radios) will fuse the DC ground as well as the positive and install an additional radio ground. As far as RF ground goes the more you have the better, as long as you don't create a ground "loop". With as much plastic and such that todays rigs have, the more each piece of metal in a vehicle is tied to the next, the better your antenna will "see" a solid mass.

 

Thanks for explaining it. You saved me some typing time. The black wire in the back is +12 volt return (GND) and the coax is a shield and has no current running thru it.
