Product Description

Product Description

GPS/GLONASS Dual-Constellation Active Antenna with 28dB LNA, Model GL-DY003

The GL-DY003 is a compact, dual-constellation active antenna designed for GPS and GLONASS satellite navigation systems, operating at the standard L1 frequency of 1575.42±1 MHz with Right-Hand Circular Polarization (RHCP). Featuring a built-in Low-Noise Amplifier (LNA) with 28±2 dB gain and a low noise figure of <1.5 dB, it provides enhanced signal reception for improved positioning accuracy in challenging environments. With excellent electrical characteristics including VSWR <1.5 and 50Ω impedance, the antenna ensures optimal performance with modern navigation receivers. The sleek cylindrical design (φ14.6×46.7 mm) offers versatile mounting via magnetic base or adhesive, making it suitable for both fixed and mobile applications. It includes a 2-meter RG174 cable with either Fakra C (blue) or SMA male connector options and features IP65-IP67 protection (excluding cable outlet) against environmental elements. Operating reliably from -40°C to +85°C with 5-95% humidity tolerance, the GL-DY003 is engineered for demanding automotive, marine, industrial, and IoT applications requiring reliable multi-GNSS positioning.

FAQ

Q: What is the advantage of supporting both GPS and GLONASS?
A: Dual-constellation support increases the number of available satellites, improving positioning accuracy, reliability, and time-to-first-fix, especially in urban canyons or areas with partial sky visibility.

Q: What power requirements does this active antenna have?
A: The antenna operates on 3-5V DC supplied through the coaxial cable from the GPS/GLONASS receiver, with current consumption between 5-15mA.

Q: Can I choose between Fakra C and SMA connectors?
A: Yes, the GL-DY003 is available with either Fakra C (blue) or SMA male connectors, allowing compatibility with different receiver interfaces commonly used in automotive and industrial applications.

Q: How should I mount the antenna for optimal performance?
A: For best results, mount the antenna with a clear view of the sky, preferably on a horizontal surface. The magnetic base allows easy installation on vehicle roofs, while the adhesive option works for non-metal surfaces.

Q: Is this antenna waterproof for outdoor use?
A: Yes, with IP65-IP67 ingress protection (excluding the cable outlet), the antenna is protected against dust and water jets, making it suitable for outdoor installations in various weather conditions.
