Product overview
Dongguan Tengxiang Electronics Co., Ltd’s TX-RT004 is an embedded high-precision GNSS helix antenna module for OEM integration. Its supplied form is a shell-less antenna component with an SMA-J male connector, screw mounting, an integrated low-noise amplifier and band-pass filters. The compact architecture is intended to fit inside proprietary housings, drone airframes and other constrained device spaces. Applications include RTK base stations and mobile units, handheld surveying equipment, GIS data collectors and agricultural machinery control boxes.
The module supports GPS L1/L2, BDS B1/B2/B3, GLONASS and Galileo, with right-hand circular polarization and millimeter-level phase center stability. Its Φ43.5 × 39.1 mm envelope and 3-M2.5*6 screw mount define the mechanical integration requirements, while the shell-less configuration calls for installation within the host enclosure. Electrical operation spans 2.2V to 16.0V DC at a working current of ≤35mA, including direct connection to 12V vehicle or industrial rails. The specified operating temperature range is -40°C to +85°C.
