In case of a natural disaster or other major event where the power grid goes down, CB radios are a great way for preppers to stay in touch with friends and loved ones who live in the same area.

CB radios are used in a variety of industries and services to enable short-distance communication. In a pinch, they can be used to get information out to the general community or to keep in contact with your family, Nowadays, you’ll often find CB radios being used in the backcountry for hunting or camping expeditions.

How Do CB Radios Work?

CB Radio stands for Citizens Band Radio and is used for high-quality short-distance communication. It is commonly used for localized communication for truckers, survivalists, emergency services, and hobbyists who enjoy collecting them. They use an 11-meter band that goes between 26.965 MHz and 27.405 MHz. Generally, they have 40 channels and that’s it.

As cell phone coverage has improved dramatically in recent years, more and more are moving in that direction. However, CB radios have some advantages over these other services.

Why Are CB Radios Good in an Emergency?

If cell phone networks and power grids fail during a major disaster, you’ll find yourself suddenly disconnected from the world. CB radios remedy that by continuing to work in these scenarios, as long as the device doesn’t get damaged.

Our communication infrastructure is more fragile than you think. During a long-term disaster, cell phone towers will be jammed, and eventually their backup generators will run out of fuel. But with a CB radio, all you need is the power from your vehicle battery or, for the portable units, some AA batteries,

The Difference Between CB Radio and HAM Radio Services

Beginners can get confused about CB and HAM radios pretty easily as they do essentially the same thing. You’re able to provide communications for emergencies and disasters. However, the differences lie in how well each of them performs that function.

Power – CB radios have a fraction of the powerful capabilities that a ham radio has. A CB radio is pretty much topped out at 4 watts for AM and up to 12 watts for a single sideband. This means the communication capabilities will only work for a few miles. HAM radios cap out at 1500 watts, making them capable of transmitting signals all across the world.

Licensing Unlike CB radios, HAM radios need a license to be operated. The FCC put this in place because of the capabilities of the HAM radio system. CB radios used to require licensing, but that was scrapped (unless you needed it for something large like a radio station).

Frequency – CB radios use channels whereas HAM radios use frequency. This means that while CB radios are perfect for local communication, HAM radios have more options when it comes to radio bands available to them.

A Short Buyer’s Guide to CB Radios

If you’re new to the world of CB radios, then the options and technical terms might be a little overwhelming at first. Luckily, the concept is easy to pick up, and this buyer’s guide will get you going in the right direction.

Single Sideband

There are two types of signals that a CB radio can transmit: AM (Amplitude Modulation) and SSB (Single Sideband). Whereas an AM signal consists of the full spectrum of channels, SSB only uses the upper or lower half (sideband) of channels, making it far more efficient.

Brand Name

For something as important as off-grid communication, it’s best to avoid the knockoffs that you can find floating around the internet. There are 3-4 major manufacturers that have a tried-and-true track record. These include Uniden, President, Cobra, and Galaxy.

RF Gain

The RF gain allows you to filter out any excessive noise by only picking up the signals closest to you. It performs the same function as a squelch, By adjusting both the squelch and the RF gain knob, you can effectively increase your range by eliminating the background signal noise.

Standing Wave Ratio Meter (SWR)

Look for a CB radio that has an SWR meter built in. This device determines how much power reaches the destination before being reflected. If your power is impeded, then they are called standing waves in that they are not radiating normally.

An SWR reading needs to be low to have optimal performance. The low reading means that your antenna is transmitting enough radio frequency power instead of it being sent back. If the SWR is too high and there is too much power being reflected, then it comes back as heat and can damage the transistor in your device.

value

Pay attention to the specifications of the CB radio you’re looking at. You’d be surprised at how many times you find a device with the exact same specifications, yet the price is higher or lower. Take the time to shop around.

Frequently Asked Questions

If you’re ready to take the dive and get your CB radio, check out these questions that newcomers typically ask as they learn their way around one of these units.

What is the average range of a CB radio?

Depending on the quality, the average range for a CB radio is between 5-20 miles. There are certain ways to increase this range through additional technology.

Can you amplify the signal?

Technically a gray area as you are limited to how much power you can transfer through the airwaves. The best legal solution is to have a strong antenna or to focus your antenna.

How many channels are available on a CB radio?

All CB radios have access to 40 channels. Some models have NOAA weather channels included for those using a CB radio in natural disaster areas.
