Short Description

The BT-410 Multi-Band GNSS Shark Fin Antenna is an active vehicle-mounted navigation antenna supporting GPS L1/L2, GLONASS L1/L2, BeiDou B1I/B2I/B2b and Galileo E1/E5b. Featuring RHCP polarization, 28 ± 2 dB LNA gain and a streamlined shark-fin housing, it is designed for reliable multi-constellation GNSS reception in automotive and professional positioning applications.

Product Overview

The BT-410 is a multi-band active GNSS antenna designed for vehicle-mounted satellite navigation and positioning systems.

Its multi-constellation design supports GPS L1/L2, GLONASS L1/L2, BeiDou B1I/B2I/B2b and Galileo E1/E5b, allowing compatible GNSS receivers to access signals from multiple global navigation satellite systems.

The antenna uses right-hand circular polarization (RHCP) and integrates an active LNA with 28 ± 2 dB gain. The antenna element provides a gain of at least 2.0 dBi, with a 50-ohm impedance and VSWR of ≤ 2.0.

A streamlined white shark-fin enclosure makes the BT-410 suitable for integration on vehicle roofs and other mobile platforms where a low-profile automotive appearance is required.

The standard configuration includes 3 m RG316 cable and an SMA-J connector, while connector configurations can be customized according to project requirements.
