The 1575.42MHz GPS/GSM Antenna is a high-reliability, dual-purpose solution engineered for applications requiring both precise Global Positioning System (GPS) data and ubiquitous GSM/2G cellular communication. This all-in-one approach simplifies deployment by consolidating two essential antennas into a single, compact, and durable unit.
Operating primarily on the GPS L1 frequency of 1575.42 MHz for location services, and simultaneously covering the key GSM/2G bands (usually 900 MHz and 1800 MHz) for data transmission, this antenna provides the crucial link for tracking, telematics, and remote diagnostics. It is equipped with the flexible and reliable RG174 Coaxial Cable and terminated with the industry-standard SMA Connector, ensuring easy, secure integration into your tracking hardware.
Key Features and Technical Versatility
This antenna is designed for professional-grade performance, combining the requirements of sensitive GPS reception with robust cellular transmission.
Precision Dual-Band Performance
Dedicated GPS L1 Frequency: Tuned precisely to 1575.42 MHz, ensuring high sensitivity and fast Time-to-First-Fix (TTFF) for accurate positioning, even in challenging environments like urban canyons or dense foliage.
GSM/2G Communication: Provides reliable connectivity across the primary GSM 900 MHz and 1800 MHz bands, enabling data reporting, command control, and basic remote communication for low-bandwidth applications.
High Sensitivity: The GPS element often incorporates a Low Noise Amplifier (LNA) to boost the weak satellite signal, ensuring superior performance and reliability where passive antennas fail.
Voltage Support: The active GPS element requires DC voltage (typically 3V or 5V) fed through the coaxial cable's center pin, compatible with standard GPS receiver modules.
Compact and Robust Assembly
RG174 Coaxial Cable: Utilizes RG174/U cable, which is favored for its ultra-flexibility and small diameter. This is crucial for routing through tight spaces, behind dashboards, or within small tracking devices where minimal bend radius is required.
SMA Connector Termination: Features the robust, threaded SMA Male or Female connector (depending on application), guaranteeing a secure, vibration-resistant, and low-loss connection to your GPS/GSM modem or tracking unit.
Durable Housing: Typically housed in a tough, compact casing (often magnetic or adhesive-backed), designed to withstand shock, vibration, and mild weather exposure in vehicle or outdoor tracking applications.
50 Ohm Impedance: The cable and connectors maintain the required 50 Ohm impedance standard for both cellular and GPS transmission.
Versatile Application Scenarios
The dual GPS and GSM capability makes this antenna assembly the cornerstone for various real-time tracking, telematics, and security systems.
1. Fleet Management and Telematics
Vehicle Tracking: Essential for commercial fleet vehicles, allowing real-time location monitoring (GPS) and the transmission of diagnostic and location data (GSM) back to a central server.
Asset Monitoring: Used for tracking high-value mobile assets such as trailers, containers, heavy equipment, and generators, providing their exact location and status updates.
Usage-Based Insurance (UBI): Integrated into dongles or modules for recording driving behavior and mileage data for insurance applications.
2. Security and Recovery Systems
Vehicle Recovery: Crucial for anti-theft systems, where the hidden antenna maintains a link to report the vehicle's location immediately if unauthorized movement is detected.
Personal Tracking Devices: Used in small, portable safety and security devices that require constant location awareness and the ability to send alerts via the cellular network.
3. Mobile Point-of-Sale (POS) and Logistics
Mobile Terminals: Providing location-based services and reliable data connectivity for mobile POS systems and handheld logistics scanners used by delivery drivers and field technicians.
Public Transport: Installing on buses or trains to enable accurate route tracking, scheduling, and two-way communication with the dispatch center.
The 1575.42MHz GPS/GSM Antenna with RG174 Cable and SMA Connector is the efficient, integrated solution that powers reliable location and data services for modern mobile and M2M applications.
