Core Specifications: Unmatched Precision and Reliability
This GNSS antenna is a professional-grade solution built for high performance and durability. Its specifications are tailored to deliver the best possible signal integrity and ease of integration into your wireless system.
Target Frequency: Precisely tuned to 1575.5 MHz—the standard L1 band for civilian GPS and the primary frequency for global positioning services. This ensures peak efficiency for satellite navigation.
High Gain Performance: Featuring a robust 4.5 dBi antenna gain, this high-gain antenna significantly improves the signal-to-noise ratio (SNR), allowing your GPS receiver to maintain a reliable lock on a higher number of satellites, even in urban canyons or under foliage.
Integrated Low-Noise Amplifier (LNA): As an active GPS antenna, it includes a built-in LNA to amplify the extremely weak satellite signals while maintaining a low noise figure, which is essential for rapid Time-To-First-Fix (TTFF) and consistent tracking.
RG316 Coaxial Cable: The signal transmission backbone is the RG316 RF cable, known for its excellent flexibility, miniature diameter, and high-temperature performance, making it an ideal low-loss cable for tight installations.
SMA Male Connector: The industry-standard SMA (SubMiniature version A) connector provides a reliable, threaded, and low-impedance interface, ensuring minimal signal attenuation and maximum mechanical stability for this RF assembly.
The Technology Advantage: High Gain and Active Design
The performance of any satellite navigation system hinges on the antenna's ability to capture and process faint signals originating from 20,000 km above the Earth. Our design prioritizes maximizing the quality of this critical RF link.
Maximizing Signal Quality with 4.5 dBi Gain
The 4.5 dBi gain figure is a key differentiator. In simple terms, gain measures the efficiency and directionality of the antenna element. By focusing its sensitivity, this high-efficiency antenna effectively boosts the power of the received GPS L1 signal. This is crucial for overcoming path loss and mitigating the effects of multipath interference, which occurs when signals reflect off surrounding objects. A higher gain means better Positioning, Navigation, and Timing (PNT) data, leading to superior location accuracy for all your geospatial applications. This directional antenna characteristic ensures superior signal capture where it matters most.
The Role of the Active GPS/GNSS Antenna
Unlike a passive antenna, an active antenna integrates a Low-Noise Amplifier (LNA) directly into the unit. The LNA's job is twofold:
Amplify: To increase the power of the incoming satellite signal as close to the antenna element as possible.
Minimize Noise: To perform this amplification without adding significant electronic noise, quantified by the noise figure.
By using an active antenna design, we ensure the signal delivered to your GNSS receiver is already strong and clean, dramatically improving its sensitivity and the overall reliability of the navigation system. This is a core requirement for professional-grade timing antenna and tracking antenna applications.
GNSS Ready: Beyond GPS
While precisely tuned to the GPS L1 frequency, the term GNSS (Global Navigation Satellite System) signifies its readiness to interface with receivers capable of utilizing other satellite constellations that operate on or near this frequency, such as GLONASS, Galileo, and BeiDou L1/B1 bands. This multi-constellation antenna capability ensures that your system remains robust and future-proof, leveraging the increased satellite visibility for improved positioning resilience and faster initialization time.
Premium Construction: RG316 Cable and SMA Termination
The longevity and performance of an external antenna are highly dependent on the quality of its accessories. We've selected the RG316 cable and SMA connector for their proven durability and signal integrity.
The Versatility of RG316 Coaxial Cable
The RG316 cable is a high-performance, shielded coaxial cable that offers a distinct advantage over standard alternatives:
Exceptional Flexibility: The small diameter and construction of the RG316 make it extremely flexible, simplifying installation and routing in tight or complex enclosures, such as within a vehicle tracking unit or a compact IoT sensor.
Temperature Tolerance: It features a PTFE dielectric which provides outstanding stability and performance across a very wide temperature range, making this RF cable suitable for everything from frigid outdoor deployments to high-heat internal component spaces.
Low Attenuation: Though small, the RG316 cable is a 50 Ohm coaxial cable designed to minimize signal loss (attenuation) over its length, ensuring that the amplified signal from the LNA reaches your GNSS module with maximum strength.
Dependable SMA Male Connector
The SMA Male connector provides the final, essential link. Its robust, threaded coupling mechanism is resistant to vibration and pull-out, a crucial feature for any mobile antenna or vibration-prone industrial application. The SMA interface is standard across the RF equipment industry, guaranteeing compatibility with virtually all professional-grade GPS receivers and wireless modules. This secure coaxial connector ensures a stable radio frequency environment, free from intermittent disconnections that could disrupt critical location services.
