Product Technical Features
The antenna utilizes multi-arm helical technology to ensure right-hand circular polarization and phase center performance, minimizing the impact of measurement errors.
The antenna unit utilizes air dielectric, offering high gain and minimal gain roll-off.
This ensures excellent reception of satellite signals at low elevation angles, ensuring reliable reception even in heavily obscured environments.
The triple-proof housing provides long-term field protection.
Key Advantages of Antenna STA-903 (Cable & Mount Design)
1, Unlimited Installation Flexibility
You can mount the antenna on the highest, most open position (away from metal or electronic interference) to maximize GNSS signal strength and positioning accuracy.
2, Universal Compatibility
The standard SMA male connector works with nearly all GNSS receivers, flight controllers, and industrial GPS modules, eliminating the need for extra adapters.
3, Stable & Vibration-Resistant
The dedicated mounting base with screw holes keeps the antenna firmly secured, preventing loosening or damage from vibration (critical for vehicles, drones, and industrial equipment).
4, Superior Weather & Environmental Protection
The fully enclosed antenna housing and sealed cable entry can achieve IP67-level waterproofing, making it ideal for outdoor, marine, or harsh industrial environments.
5, Simplified Product Design for Host Devices
No need to reserve large openings or antenna mounting space on your device; only a small cable pass-through hole is required, reducing structural and waterproof design complexity.
