Description
Dual-Band GNSS GPS L1/L5 Active Antenna
The WK-GN23FL15 is a compact dual-band GNSS GPS L1/L5 active antenna designed for high-precision positioning, navigation and satellite-based communication applications. It supports a wide GNSS frequency range of 1164-1278 MHz and 1559-1610 MHz, covering the major L5 and L1 frequency bands used by modern GNSS positioning systems.
Featuring RHCP (Right-Hand Circular Polarization) and an antenna gain of ≥2 dBi, the antenna is optimized for receiving circularly polarized signals from GNSS satellites. Its ≤1.5 dB axial ratio at Zenith provides excellent circular polarization performance and helps maintain reliable satellite signal reception.
The integrated low-noise amplifier (LNA) provides 28 ±2 dB typical gain at 25°C, with a low noise figure of ≤1.5 dB, helping compensate for cable and system losses while improving the quality of received GNSS signals. The LNA operates from 3.0-12.0 V DC with a maximum working current of 45 mA.
With a 360° horizontal 3 dB beamwidth, 50 Ω impedance and VSWR ≤2.0 typ., the WK-GN23FL15 provides broad azimuth coverage and stable RF performance. Its compact Φ23 × 55.6 mm form factor makes it suitable for integration into space-constrained GNSS positioning equipment.
The antenna uses a durable ABS+PC radome and provides IP67 waterproof protection. With an operating temperature range of -40°C to +85°C, it is suitable for demanding outdoor and industrial environments.
