Introduction
CB radio (Citizens Band Radio) is a license-free radio service in the 11-meter band around 27 MHz. It enables direct communication between radio subscribers without the Internet, mobile network or amateur radio license. CB radio is used both mobile in the vehicle and stationary or portable and is particularly popular with travelers, outdoor activities, in technical hobby areas and for local communication.
This page provides an overview of the possibilities of CB radio, legal differences between countries, recommended devices as well as German-language information sources and YouTube channels.
What is CB radio?
CB radio is a generally accessible radio service with defined frequencies and performance limits. In most European countries it can be used free of charge and registration.
Basic data (Europe, general):
- Frequency range: 26.965 MHz – 27.405 MHz
- Channels: 40
- Modulation types: FM, AM, SSB
- Maximum transmission power:
- FM / AM: 4W
- SSB: 12W PEP
CB radio is suitable for short to medium distances. Under favorable radio conditions (Sporadic-E, fading), Europe-wide connections are also possible.
Application options for CB radio
Mobile communication
CB radio is often used in vehicles, for example to coordinate several vehicles, for traffic information or as an independent means of communication when traveling.
Stationary operation
With a permanently installed antenna, the CB radio can be operated from home. This allows for greater range and more stable connections.
Outdoor and leisure
When camping, hiking or at events, CB radio can be used for group communication, especially where cell phones are not available.
Technology and radio hobby
Many users are concerned with antenna construction, radio technology, range optimization and radio operation under special propagation conditions.

Antennas and accessories
- Magnetic or fixed mount antennas (1/4 λ, 5/8 λ)
- SWR measuring device for antenna adjustment
- Coaxial cable with low attenuation
- Vehicle mounts and external speakers
Operating instructions and technology
- Only approved devices may be used.
- Power amplifiers are not permitted in CB radio.
- SSB operation is only permitted within the permissible performance limits.
- Radio communication should be considerate and interference-free.
CB radio thrives on mutual respect, technical discipline and the common interest in wireless communication.
Conclusion
CB radio is a simple and low-threshold entry into the world of radio communication. Without a license, with manageable costs and a wide range of possible uses, it offers both practical benefits and technical appeal. Especially in combination with good antenna technology and in-depth knowledge, CB radio remains a lively radio hobby today.
