GPS GNSS GLONASS TETRA FME 76° Roof Antenna

Roof antenna GNSS GPS/GLONASS/Galileo/BeiDou TETRA 76° FME ATTB 3801.01 ATTB 3801.01 is a professional 16V roof antenna designed to support systems GNSS, GPS, GLONASS, Galileo, BeiDou and TETRA The product comes from a German manufacturer Antennentechnik Bad Blankenburg, which has been developing high-quality antenna solutions "Made in Germany" since 1919. This antenna was designed for automotive location systems and communication in the TETRA band. It is suitable for special vehicles, fleet vehicles, technical vehicles, service vehicles, and installations requiring stable satellite positioning and reliable radio communication. GNSS and TETRA Roof Antenna: The ATTB 3801.01 combines an active GNSS antenna with a TETRA communication channel. This allows a single roof antenna to support satellite navigation and mobile communications in the 380-430 MHz band. The active GNSS antenna uses +3V to +5.5V phantom power. The TETRA channel supports power up to 25W, making this model suitable for demanding communication installations in vehicles. Key advantages of the ATTB 3801.01 antenna

Important Installation Information: To achieve the best signal quality, ensure proper grounding of the antenna base or ground strap. Good contact with the vehicle ground is essential for stable operation of GNSS and TETRA installations. During installation, remove paint from the contact points using appropriate workshop tools. Then, protect the area from corrosion with contact paste. For better contact, also ensure proper connection of the antenna rod thread and the antenna base. If reception problems occur, check the antenna cable, adapters, and the quality of the connections. It is also worth verifying that additional LED lighting, USB chargers, voltage converters, power supplies, or digital power amplifiers are not causing interference. Technical Data
