If you have a CB radio, you probably know that it works on low frequencies. Add to this a big city life and your CB radio becomes almost useless.
Is it possible to fix this? Yes, it is.
You have two options: to go out of town or to the sea (you will hear it very well there) or use a CB amp.
The prospect of going to the sea to ensure that your radio becomes useful is not very attractive. I think you thought about using a CB amplifier. And here is why that is right
Why should I use a CB amplifier?
A CB linear amp is a very useful thing that effectively amplifies the signal from the radio. How effective is it?
I will assume that CB radio has power up to 10 or even 12 watts. That’s not bad, but you can get all 15 or even 18 watts of power with a CB linear amplifier.
Plus, if you use a CB amplifier, then you do not need to go to another location where a person’s foot doesn’t go, because you will get a connection even up to 7k or 8k miles away.
A CB amplifier is a terrific thing and would be even better if it were legal everywhere (please check the information about the legality of CB amp using in your state/country and eschew any playing with the law).
Yes, being caught using the CB amplifier you can’t escape the fine. We may be indignant for a long time, “What have we done?” But this does not change the fact that the law prohibits exceeding the allowable output power of more than 12 watts.
Fortunately, this is not illegal everywhere and so I continue the guide.
Are you already going to the store for a CB amplifier for your radio? Do not rush! You still need to check something.
Is CB radio intended for amplifier power?
The matter is that different CB radios have a different power threshold. And it is quite possible that your radio squeezes out its maximum power and no amplifier can cope with it. So, what does it mean?
It means that you must be sure that your CB antenna is OK and that can be connected to an amplifier.
If everything is good, there is no reason why you can postpone the search for CB amplifier.
What Types Of CB Amplifiers Exist?
In retail or online stores you will find three types of CB radio amplifiers:
- CB Linear Amplifiers
- Valve RF Amplifiers (tube amplifiers)
- Common-emitter Amplifiers
CB Linear amplifier is good because it perfectly recovers the outgoing radio signal.
Valve RF amplifiers are suitable for very powerful (professional) radios.
And common-emitter amplifiers are good at amplifying the weak incoming signal that the radio picks up.
But 9 out of 10 (if not all 10) people who need an amplifier for CB radio go to the store only for a CB linear amplifier. Why?
The point is that a linear amplifier is better than the others for two reasons: a) this type of amplifier has excellent characteristics b) this amplifier is able to overcome hundreds of miles at the highest power.
So, if you are sure that all is ready about the CB radio and it is suitable for an amplifier, we proceed to the main point:
How to hook up a CB Linear Amplifier?
First, you do not have to worry, it’s simple. Be careful and do not overuse power (as I said, this is not legal).
The first thing to do is to connect the CB radio to the base that you keep at home or in the car or everywhere you want.
At this stage, you must be sure that the antenna wave has a straight vertical position.
I also advise you not to connect a CB Linear amplifier if the standing wave ratio is not good enough because it is a direct way to break the radio.
Plus, be sure that SWR is not lower than 1: 5. Why is it important? Because the indicator above it can break the transistors. That’s why you need the best swr meter.
Continuing to hook up the CB amplifier, move it close to the base to which you connected the radio.
For example, if the CB radio is connected to the car, then I would put the radio on the amplifier. There is an option to put the amplifier on the floor – this is good if the CB radio is in the car or at home.
The second step
The next step is to disconnect the coaxial cable from the CF. And this cable must be connected to an “input” (or “output”) on the amplifier.
Before you connect the coaxial cable put the amplifier next to the radio, as I requested above.
The third step
Included with the amplifier should be a patch cord that has two ends. One end is to connect to the CB radio, and the other end is to the amplifier (the connection point is called “input”).
Do what this patch cord is intended for – connect one to the other.
The fourth step
Is all ready? If it is, connect the amplifier to the power supply. But here everything is not darkly.
If you use a standard CB amplifier, it is enough to insert the plug into the socket for connection. And ta-dam! The amplifier will be turned on.
There is a second option – your professional amplifier and for a more serious level than the home version. In this case, you will need to work with the wires. Remember: red is positive and black is negative.
The final stage
Now check how it works and does it work or not.
If the power of the radio has not changed, then 1) you did something wrong and you need to repeat the connection; 2) problems with the amplifier; 3) the CB radio you use cannot be used in tandem with the amplifier at all.
