Selecting a CB Radio

Selecting a CB Radio

The most important factor to understand when choosing a radio is that all CBs, regardless of their price, are limited to 4 watts of transmission power by the FCC. This means that a $50 CB radio and a $200 chrome plated CB radio with every imaginable feature will have exactly the same transmission power. While a radio can be “peaked and tuned”, a process that increase a CB’s performance, all CB radios will have the same transmission power out of the box. There are a number of available radios on the market including Cobra CB radios , Galaxy CB radios , Uniden CB radios , and Midland CB radios.

What primarily differentiates CB radios from each other is their features, not their output strength. CB radios come with a number of features, the most popular of which we’ve outlined below:

Squelch Control - This control sets the break-point at which a CB radio outputs a signal. In effect, it keeps the operator from constantly having to listen to static and only activates the speaker when a transmission is received. This is a standard feature and is included with nearly every CB radio sold.
PA Capability - Allows use of the CB radio and microphone as a transmitter for a public address system. This requires a PA horn (usually not included) that can be mounted under the hood or on top of the vehicle.
RF Gain - Allows the operator to filter the type of transmission a CB radio receives based on signal strength. It’s useful to block out faint transmissions to eliminate background noise when talking with someone with a strong signal. This feature can also be used to pull-in and better hear weak signals.
Automatic Noise Limited (ANL) - Filters out static, engine noise and other interference from the reception signal to improve reception sound quality.
Weather Capabilities - CB radios with this feature have the ability to access local NOAA radio stations for real-time weather reports and updates.
Instant Channel 9 & 19 - The ability to quickly jump to two of the most popular channels: Channel 9 (Emergency) and Channel 19 (Highway / Truckers).
Nightwatch and/or Backlit Displays - A number of higher priced models include a backlit radio display for convenient operation at night. This is an invaluable feature if a radio will be used extensively at night or in dark conditions.

When choosing a CB radio and its corresponding features, it’s important to focus on how and where the CB will be used. Specific vehicle owners tend to want different features in a CB radio. Jeep and Off-road drivers usually have smaller vehicle cabs and tend to choose compact CB radios due to space constraints. The Uniden 510XL and Cobra 75 CB radio are both popular choice with off-road drivers due to their compact size.

There are a wide range of features available for CB radios and only the individual can best determine which feature set best suits their needs.
As all CB radios are limited to 4 watts of output, the biggest factor determining radio performance is the antenna. A cheap radio and correctly installed quality CB antenna will perform infinitely better than an expensive radio and a poor antenna setup.
