How to tune a CB antenna without an SWR meter?
This is a complete step by step procedure to guide you through how to tune a CB antenna without an SWR meter. However, every vehicle has a different procedure for doing every single task. This is still the most common way of tuning. Before jumping into the procedure, let’s understand the basics.
What is a CB antenna?
As you can understand from the name, a CB antenna is a type of antenna that has something to do with receiving and sending radio signals. The Full form of the acronym CB is Citizen Band. There are a variety of bands, depending on the utility. Citizen band refers to the bandwidth that is accessible and usable by the citizens, aka general people.
A CB antenna captures radio signals and converts that signal into an electrical signal to relay through a hearing device. Again, it converts the electrical signal to radio signals and then transmits to other receivers.
Tuning only is necessary when you are transmitting signals to other receivers. That means when you want to use your CB antenna to transmit signals, you have to tune it first.
What is an SWR Meter?
A standing wave radiometer, aka an SWR meter, is a meter that measures the standing wave radio signal in any transmission line. If you know the guitar tuner’s basics, you would know that we use it to tune the guitar string for playing the perfect cord. An SWR Meter does the same job while you are setting up a transmission line.
In other words, an SWR meter makes the transmission line sit on the perfect standing radio wavelength so that the transmission can be as seamless as possible. The easiest way to describe that is it’s a tuner for your antenna.
Can you tune a CB antenna without an SWR meter?
Before making the jump to how, let’s understand whether or whether you can do it or not. A guitar tuner has become mandatory while tuning a guitar because it makes the procedure easier for everyone.
Similarly, an SWR meter makes the tuning procedure of a CB antenna easier and better. An SWR meter is constructed to assist the tuning procedure measuring the smallest gap between radio waves. If you use an SWR meter to tune your Cb antenna, you will get the maximum accuracy possible.
But an SWR meter is not essential for just tuning the CB meter. You can tune your CB meter without the help of an SWR meter.
Should you tune a CB antenna without an SWR meter?
The fact that you can do something does not necessarily mean you should do that. To get the best results out of something, you need some incentives and a few tools to make it happen. In tuning a CB antenna, to get the best results, an SWR meter is a must.
So, if you think you need to tune your antenna accurately, get an SWR meter. Also, the procedure is more effortless that way.
How to tune a CB antenna without an SWR meter?
There are a few things that you need and a few steps that you have to follow. Let’s start with the necessities first, and then we will move forward with the process step by step.
What do you need?
- Clear open space, having at least 40 meters span. Best if it’s an open field
- A second Cb antenna which is tuned
- A helper
That’s all you need. Now read through and follow the process carefully. You don’t want to make a mistake unless you have the patience to start from the top again.
- Step 1: Selecting the open place
The first step is crucial. It would be best to have an open place where there are no tall buildings and tall trees that might obstruct your signal. The radio signal sent from your Cb antenna to the second CB antenna should have a seamless pathway.
If there’s a building or tree between, the signal might not relay properly even if your radio is tuned accurately. So, try and fin an open place where you can set both antennas at least 40 meters apart.
- Step 2: Getting your antenna ready
Usually, to ensure that your antenna can work properly, you should keep the power level low while tuning it. In that way, you will get the best reception and transmission even if your antenna’s power level takes a hit at times.
It would be best to connect a microphone with which you will talk, and your helper will receive the signal on his antenna. He then can signal you whether he’s getting the reception properly or not.
- Step 3: Choose a channel between install channel 9 to 19
Now, to check your antenna’s reception, you and your helping hand have to be tuned in to the same channel. The best option for you is to tune between instant channels 9 to 19. These channels have the finest reception quality.
Thus, to check your device’s accuracy, no other channel can give you a better hand. Now, all you have to do is switch on your microphone and talk.
- Step 4: Check the reception
This is the final step of the total procedure. All the necessary technical work has been done. Now, your assistant has to confirm whether he’s getting a clear transmission or not.
If he signals you that he’s getting a perfect transmission, your tuning procedure is done.
This is the proper procedure for tuning a CB antenna without an SWR meter. It will be best if you follow the steps accordingly. Otherwise, your tuning may not be perfect, and when it’s time for your utility, you will not get the best service.
So, try to follow the steps correctly to ensure the best tuning of your CB antenna without an SWR meter.
