Antennentechnik Bad Blankenburg has stood for radio-based networking solutions with the highest quality and reliability "Made in Germany" with its own research, development and production since 1919.

Reliable and powerful antennas with optimum signal quality are indispensable for communication, infotainment, navigation and the networking and control of machines using communication standards such as 5G, LTE, UMTS, GSM, WLAN, BT, GPS, DAB+ and TETRA.

In addition to standard solutions, the ATTB range also includes customised special developments and applications including for the automotive industry.

Close cooperation in research and development with leading organisations and research institutions has resulted in over 40 patents and numerous innovations to date.

The entire production process for the broad portfolio of vehicle antennas and antenna accessories for many popular vehicles is certified in accordance with automotive industry standards and the quality of the antennas is continuously checked using our own measuring stations, from product development to ongoing production and final inspection.

Note:

DAB+ reception with optional antenna splitter*

In case of reception problems:

check antenna cable and antenna adapter

check vehicle for faults due to retrofit LED lighting
check vehicle for faults due to retrofit voltage converter / power supply units / USB charging adapter
check vehicle for faults due to retrofit digital power amplifiers

to optimise the reception of antennas, always ensure an optimum ground connection of the antenna base or the ground strap during installation.

remove existing paint at the contact points with workshop tools and protect against corrosion with suitable contact paste and also treat the antenna rod thread and the antenna base thread to optimise contact.
