The TX-GR04-A is a professional-grade, large-scale active antenna independently developed by Tengxiang Electronics. Featuring a broad Ø154mm aperture, it is engineered to capture even the weakest signals, making it a premier choice for RTK base stations, structural monitoring, and precision agriculture. Unlike mass-market clones, we offer "Bespoke Engineering" to optimize RF matching and hardware integration specifically for your application.
1100% In-house R&D (Customizable)
Original RF design allows for deep customization. We fine-tune the antenna's performance based on your device's internal environment.
2Elite Satellite Tracking (44 Satellites & 77 Channels)
Advanced hardware allows simultaneous tracking of 44 satellites, drastically reducing RTK initialization time and ensuring stable locks.
3Proven Field Performance (Dongguan Test)
Tested at coordinates 22.816644, 113.803939. Successfully completed tests in a "canyon" environment surrounded by factory buildings on three sides.
4Superior Interference Rejection
Features an integrated LNA and premium filters with ≥30dB out-of-band rejection to maintain signal lock in noisy industrial areas.
5Rugged Construction
Equipped with a TNC-K connector and IP67-rated UV-resistant housing. Tested for 48H Salt Spray for long-term outdoor reliability.
