Dual-Function Performance: GPS and GSM Connectivity
The core strength of this dual-band antenna lies in its ability to master two critical yet distinct RF frequency bands through a single, compact device.
Precision GPS L1 Band Tuning: Optimized for 1575.5MHz, this navigation antenna is designed to capture the weak GPS satellite signals efficiently. The integration of an active GPS antenna element includes a high-quality Low-Noise Amplifier (LNA). This LNA amplifies the signal while maintaining a low noise figure, which is essential for rapid Time-To-First-Fix (TTFF) and consistent positioning accuracy.
Robust GSM Cellular Link: The communication antenna is also capable of transmitting and receiving across key GSM cellular frequency bands (e.g., 850/900/1800/1900 MHz). This functionality provides the necessary data conduit for transmitting location-based services (LBS) data and operational telemetry back to a central server. This makes it a crucial cellular antenna for any M2M (Machine-to-Machine) application.
Flexible Gain (3-5 dBi): The specified 3~5 dBi antenna gain ensures a strong, reliable signal in diverse conditions. The high end of the gain range maximizes signal strength for both navigation and data, helping overcome path loss in challenging RF environments like urban canyons or remote areas. This is a versatile broadband antenna capable of adapting to various installation needs.
Connectivity and Installation: The RG174 and SMA Advantage
The integrity of any RF system is determined by the quality of its components. We have selected industry-proven materials to ensure maximum signal transmission and installation convenience.
The Flexibility of RG174 Coaxial Cable
The choice of the RG174 coaxial cable is strategic, balancing electrical performance with physical properties essential for modern wireless deployments.
Miniature and Highly Flexible: The small diameter and construction of the RG174 cable make it exceptionally easy to route and integrate into tight or complex enclosures, such as within vehicle dashboards or compact IoT sensor chassis. This flexibility is key to simplifying installation for this GPS RF component.
50 Ohm Impedance: The cable is precision-engineered to maintain a standard 50Ohm impedance, ensuring efficient power transfer and minimizing signal reflection when matched with standard RF equipment and wireless modules.
Durable and Practical: As a widely used RF cable, the RG174 provides a balance of low signal loss (attenuation) and physical robustness, making it suitable for both internal and moderately exposed external antenna installations.
Secure Termination with the SMA Male Connector
The SMA (SubMiniature version A) Male connector is the industry benchmark for reliable, semi-precision RF interconnection.
Vibration-Proof Connection: The threaded coupling mechanism of the SMA connector provides a secure physical lock. This is critical for mobile antenna applications where constant movement, shock, and vibration could otherwise lead to intermittent signal loss.
Low-Impedance Interface: This coaxial connector ensures a low-impedance connection, vital for preserving the quality of the amplified satellite signal and the integrity of the cellular data link.
Universal Compatibility: The SMA interface is standard across professional-grade GPS receivers, GSM modems, and other RF components, guaranteeing easy and reliable integration into your existing wireless system.
Ideal Applications: Where Reliability is Essential
This professional-grade antenna is the ideal choice for developers and integrators building solutions that rely on continuous, accurate location services and constant mobile connectivity.
Fleet Management Systems: Providing high-accuracy vehicle tracking and immediate data reporting via the GSM network for logistics and transportation.
Telematics and Remote Diagnostics: Enabling real-time monitoring of vehicle performance and location, often operating as a key external antenna solution.
Industrial IoT (IIoT) Gateways: Serving as the singular, reliable wireless link for remote monitoring stations that require both location-based services (LBS) and data backhaul.
Security and Asset Tracking: Deployable on non-powered or portable assets, offering the versatility of multi-frequency antenna operation for constant asset awareness.
By choosing our 1575.5MHz GPS/GSM Antenna, you are investing in a powerful, versatile RF component that consolidates your wireless infrastructure. The combination of wide gain flexibility, premium RG174 coaxial cable, and the robust SMA connector ensures superior performance and hassle-free integration for all your global navigation and mobile communication needs.
