Module Overview: The AH612 GNSS high- antenna utilizes multi-feed technology to support L1, L2/L5, and L-band satellite navigation signal reception for the Beidou GPS, GLONASS, and systems. Its built-in multi-stage filter and low-noise amplifier provide excellent out-of-band rejection and strong anti-interference capabilities, ensuring operation in harsh electromagnetic environments. It meets current demands for multi-system compatibility and high- measurement. Antenna Characteristics Supported Satellite Signals: GPS: L1/L2/L5, GLONASS: L1/L2/L3, BDS: B1/B2/B3 : E1/E5/E6, L-band Maximum Gain: ≥2.5dBi Polarization: Right-Hand Circular Polarization (RHCP) Antenna Ratio @ : ≤1.5dB Horizontal Coverage: 360° Characteristic Impedance: 50 ohms Low-Noise Amplifier Characteristics: LNA Operating Frequency Band: 1164MHz-1278MHz, 1525MHz-615MHz LNA Gain: 35 ± 3.0dB (Typ. @ 25°C) Group Delay Variation: ≤5ns Noise Figure: ≤1.5dB @ 25°C, Typical Output Standing Wave Ratio: 1.8:1 Typ. 2.0: 1max Operating Voltage: 3.0~12VDC (33V or 50V recommended) Operating Current: ≤45mA Color: White Material: ASA+Aluminum Case Package Contents: 1 * Antenna Only the above package content, other products are not included.
