Overview

Beitian BT-2720 is a GNSS high-gain built-in ceramic active antenna with an RG1.13 coax lead and IPEX connector. This product series includes multiple antenna models (select by model option) covering different GNSS bands/constellations for integration into compact equipment such as drones and positioning/measurement devices.

Key Features

Built-in ceramic active antenna design with LNA (model-dependent specifications listed below)
RG1.13 coax cable, 5 cm length (listed for the models in the datasheet)
IPEX connector (listed for the models in the datasheet)
Support for multiple GNSS systems/bands depending on selected model (e.g., GPS/BDS/Galileo/GLONASS/QZSS/IRNSS)
Customization: a variety of connectors and cable types are available; cable length/connector wires may require additional customization (contact [email protected] or https://rcdrone.top/ for details)

Note from provided text: the antenna can be used to replace BT-T042, and cable length/connector wires need additional customization.
