Like other components, a car radio antenna needs to be appropriately grounded. Otherwise, you will hear more static noise due to high SWR (standing wave ratio) levels than music. In addition, bad grounding decreases the performance of car radio.
Why does a car radio antenna need to be grounded?
The ground of an antenna needs to be attached to the car in such a way that the voltage of the antenna can connect to the earth. This connection allows the earth to receive and store excess voltage rather than the extra voltage bouncing back through your antenna and radio.
How do you ground a car radio?
He knows why electrical codes do not allow the grounded circuit conductor to be interrupted and must be solidly bonded. Connect your radio's negative power wire to the vehicle chassis as close to the radio as possible using a hard point like a seat bolt or ground terminals provided by the auto manufacture.
How dangerous is it to plug in a car radio?
Not only is it dangerous, with a portion of all vehicle current flowing through you radio is called Common Mode Noise, Can be bad enough to render your radio useless. The proper termination points for Positive and Ground. For Positive directly to the Battery Term post with a fuse as close as possible to battery.
Should I wire my Radio to the battery or chassis?
A radio can be a fairly heavy load as car accessories go, so you want to avoid any voltage drop you can, and the chassis may not give you the best conduction to the battery. Neither of these is a reason to wire specifically to the battery per se, only to avoid using a completely different conductor (the chassis).
How can I tell if my car radio is grounded?

Does radio need ground?
The ground in a radio is only required for safety when there are voltages in the radio that are dangerous, such as the mains supply or plate voltage of a valve, so that if something with high voltage accidentally touches the metal case inside for example, the high voltage will short out to ground and blow the fuse, ...
How do you ground a car radio wire?

What needs to be grounded on a car?
A basic ground system is as follows: Always use a heavy ground cable and connect one end to the negative battery terminal, and the other end to the starter motor or engine block as close to the starter as possible. This will insure the correct ground path to the starter motor.
Can you ground a radio to the battery?
Never ever connect your radio or amp directly to the vehicle battery. You always ground to body of the vehicle. Positive can go to battery but best to follow manufacturer on location. If your new radio comes with a fuse on the ground, cut it off so as to only fuse the positive lead.
What happens if antenna not grounded?
If you do not have a correct path to ground, your antenna will most likely be an attractant to lightning! As the wind blows, airborne dust particles collide with your metal antenna and mast. these collisions build up a static charge.
How do I ground my stereo?
How to Ground a Stereo ReceiverChoose an adequate ground. The household metal that attaches directly into the ground is typically a cold water pipe. ... Cut ground wire to adequate length. ... Strip both ends of the wire. ... Attach wire to receiver. ... Attach wire to best grounding source. ... Test the system.
Is it better to ground to battery or chassis?
Despite common belief, the battery ground is NOT the best place to ground accessories. The battery ground to body/engine/chassis is certainly required in order to complete the circuit which makes up the vehicles ground path.
What happens if ground wire is not connected?
The appliance will operate normally without the ground wire because it is not a part of the conducting path which supplies electricity to the appliance. In fact, if the ground wire is broken or removed, you will normally not be able to tell the difference.
How many grounds does a car need?
There should be 3 grounds from the battery negative.
Where is the earthing point on a car?
Connect the black jump lead's crocodile clip to the negative (-) terminal of Car 2's battery, then the other end to an earthing point on Car 1 – this is usually found at the end of the negative lead and is bolted to a solid part of the chassis.
Why does a radio still operate?
It protects nothing. Remove the fuse, and the radio still operates because it is using the coax shield for DC power. The fuse that protects both positive and negative wires is the positive fuse. It is a Grounded system where one circuit conductor is bonded to Ground like a frame of a vehicle.
What is grounded conductor?
In an AC system, the grounded circuit conductor is Neutral. The whole point of a Grounded System is to facilitate simple, cost-efficient, and effective over-current protection of the circuit conductors. Only requires the ungrounded circuit conductors to have a breaker or fuse located at the feed point.
Why run direct to battery?
There are two reasons for the advice to run direct to the battery: Minimize the area enclosed by the power connections. This reduces both interference picked up by the wiring, and inductance (which is undesirable in power supply connections). Minimize resistance.
Can you connect a negative to a battery?
Never connect Negative directly to battery and never fuse the Negative as doing so is extremely dangerous. Doing so puts your radio in Parallel with the Battery Bonding Strap to the chassis. That means a portion of all the automobile electronics systems current is flowing through your radio including the Starter.
Can you wire a radio to a battery?
A radio can be a fairly heavy load as car accessories go, so you want to avoid any voltage drop you can, and the chassis may not give you the best conduction to the battery. Neither of these is a reason to wire specifically to the battery per se, only to avoid using a completely different conductor (the chassis).

So I'm new and this is a easy answer for most of you guys probably. I got my first cb radio. I plugged it in. I can hear people. But I can seem to broadcast. I have the antenna just sitting on the roof it's fiberglass. I've been reading it needs to be grounded.

I was thinking about stopping by a cb shop. Think ill just walk up and ask them. I have no clue ha. Thanks.

This is the best job I have had. I have been here just over 2 years and have 3 CPM in raises, get great miles and get home on time unlike other carriers I worked at. My last job got me 2000 miles a weak and home a week late. My dispatcher AJ is cool, he takes care of all of my needs and deals with me.

I have the antenna just sitting on the roof it's fiberglass. I've been reading it needs to be grounded. If I sit it on some metal will that work or should I leave the antenna there and run some wire to somewhere to ground it ?
