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.

Details

Multiple connector types and cable lengths are available for the BT-2720 series to match different GNSS receiver boards and builds.

If you need a different connector, cable type, or lead length than the standard RG1.13 5 cm IPEX pigtail, customization is supported.

Active ceramic design with an integrated LNA helps maintain stable GNSS reception; band support varies by the model option selected.


Designed for compact installs where low power draw matters, with a wide input range commonly used in drones and embedded GNSS devices.


A compact patch-and-cable assembly with IPEX connection makes integration straightforward for drones, dash cams, and other positioning equipment.


Mechanical dimensions and environmental ranges are provided to help confirm fit in tight enclosures and performance in outdoor installations.
