In today's connected world, reliable and precise location data is indispensable for everything from fleet management and asset tracking to advanced telematics and drone navigation. Our 1575.42MHz (L1 Band) GPS Antenna with 4-5dBi Gain and RG174 Cable is engineered to provide superior satellite signal acquisition and tracking performance. Optimized specifically for the GPS L1 frequency, this antenna combines a robust high-gain element with a flexible, low-profile cable assembly, making it the ideal solution for reliable positioning in demanding mobile and fixed applications.
Optimized for GPS L1 Signal Integrity
The performance of any GPS system hinges on the antenna's ability to cleanly and efficiently capture the faint satellite signals. This antenna is designed for maximum efficiency at the fundamental GPS L1 frequency.
Dedicated 1575.42 MHz Tuning: The antenna is precisely tuned to the 1575.42 MHz frequency of the Global Positioning System (GPS) L1 band. This singular focus ensures extremely high efficiency and gain at the critical operating frequency, minimizing out-of-band noise and maximizing the Signal-to-Noise Ratio (SNR).
4-5dBi High Gain: Featuring a moderate to high gain of 4 to 5dBi, the antenna significantly boosts the weak incoming satellite signals. This high gain is critical for applications where the receiver is located indoors, the antenna placement is partially obstructed, or rapid signal acquisition (Time-To-First-Fix or TTFF) is required.
Right-Hand Circular Polarization (RHCP): GPS satellites transmit signals with Right-Hand Circular Polarization (RHCP). Our antenna is designed to efficiently receive RHCP signals, providing the best possible coupling with the satellite's transmitted wave. This polarization matching is crucial for minimizing multipath interference and ensuring stable signal lock.
Active Design with LNA: This antenna is typically an active design, incorporating a high-quality Low Noise Amplifier (LNA) directly within the antenna housing. The LNA boosts the signal immediately upon reception, compensating for cable losses and significantly improving the overall sensitivity and performance of the GPS receiver, particularly when longer cable runs are necessary.
Flexible and Durable RG174 Cable Assembly
The choice of cable and its termination is crucial for maintaining signal quality from the antenna element to the receiver module, especially in space-constrained installations.
RG174 Coaxial Cable: The antenna is integrated with the popular RG174 coaxial cable. RG174 is selected for its excellent balance of flexibility, small diameter, and acceptable loss characteristics over short-to-moderate lengths.
High Flexibility: The small diameter (approx. 2.8mm) and flexible nature of the RG174 cable make it exceptionally easy to route through tight spaces, around corners, and into confined enclosures, which is typical for automotive, telematics, and small asset trackers.
Low Profile: Its diminutive size minimizes bulk and weight, which is advantageous for portable equipment and installations where aesthetics or space are a concern.
Customizable Length and Connector: The RG174 cable assembly is often available in custom lengths to suit specific installation requirements. It typically terminates with a common RF connector such as SMA, SMB, MCX, or FAKRA, ensuring direct compatibility with virtually all commercial and industrial GPS receivers and modules.
Professional Termination: The cable is professionally terminated to the antenna and connector, guaranteeing a robust, low-impedance connection that prevents signal degradation and ensures a durable mechanical link.
Rugged Construction for Diverse Applications
Built to perform reliably under demanding conditions, this GPS antenna is suitable for a vast array of critical positioning and timing applications.
Outdoor/Mobile Ready: The antenna element is housed in a rugged, weather-resistant casing, often with a magnetic base or screw-mount capability. The housing is typically rated for high ingress protection (e.g., IP65 or IP67), making it resistant to dust, moisture, and water spray, suitable for permanent outdoor vehicle or asset mounting.
Wide Operating Temperature Range: The internal electronics, including the LNA, are designed to operate consistently across a broad temperature spectrum, from freezing cold to intense heat, ensuring reliable service in any climate.
Applications:
Vehicle Tracking and Telematics: Providing reliable location data for fleet management, navigation, and insurance-based services.
Asset Monitoring: Deploying on containers, construction equipment, or remote generators where consistent tracking is essential.
Timing and Synchronization: Used in base stations, data centers, and network equipment that rely on precise GPS time signals for synchronization.
Security and Surveillance: Integrated into systems requiring continuous, accurate geographical data for monitoring and control.
Choose our 1575.42MHz GPS Antenna with RG174 Cable for an active, high-gain solution that delivers superior satellite lock performance, packaged in a flexible, rugged assembly ready for your most challenging location-based applications.
