High Gain 28dBi IPEX connector GPS L1 Antenna GL-C033

Product introduction

1.Ultra-High Gain 28–30 dBi with Built-in LNA – Integrates a premium low-noise amplifier that dramatically boosts weak GPS signals. This ensures fast Time-To-First-Fix (TTFF) and stable continuous tracking, making it perfect for high-precision applications where signal strength is critical.

2.Dual Connector Design (SMAJ + IPEX) – Comes equipped with both a standard SMAJ female port for external bulkhead mounting and an IPEX (U.FL) connector for direct on-board module integration. This dual-interface design eliminates the need for additional adapters and simplifies your hardware architecture.

3.Miniature Form Factor (25×25×4 mm) – Engineered for space-constrained designs. Whether inside a slim handheld device, a compact Anti jamming antenna fuselage, or a dense IoT PCB layout, this tiny patch antenna fits effortlessly without compromising performance.

4.Excellent Signal Integrity (VSWR ≤ 1.5) – Features an exceptionally low Voltage Standing Wave Ratio, ensuring maximum power transfer and minimal signal reflection. This protects your RF front-end circuitry while delivering cleaner, more accurate satellite data.

5.Robust 50W Power Handling – Supports a maximum input power of up to 50W, providing a durable RF solution that maintains consistent performance under varying power conditions in industrial and aviation environments.

FAQ

Q: What is the center frequency of this antenna?

A: It is precisely tuned to 1575.42 MHz, which is the standard GPS L1 frequency band.

Q: Why is the gain so high (28–30 dBi) for such a small antenna?

A: The high gain is achieved through an integrated active LNA (Low Noise Amplifier). The actual passive patch gain is lower, but the built-in amplifier boosts the overall system gain to 28–30 dBi.

Q: Which connectors are included with the GL-C033?

A: The antenna features both an SMAJ connector (female thread, suitable for external chassis mounting) and an IPEX (U.FL) connector for direct internal module connection.

Q: What are the exact dimensions?

A: The antenna measures 25 mm × 25 mm × 4 mm (Length × Width × Height).

Q: Does this antenna work with GLONASS or BeiDou satellites?

A: While it is specifically optimized for GPS L1, it may partially pick up other L1-band signals. However, for optimal multi-constellation (GPS+GLONASS+BeiDou) performance, we recommend a dedicated multi-band antenna.

Q: Does this antenna require external power?

A: Yes. As an active antenna, it requires a DC bias voltage (typically 3–5V) supplied through the coaxial cable to power the internal LNA. Please ensure your GPS module has an active antenna bias output.
