AH612-GNSS High-Precision Measuring Antenna

Right-Hand Circular Polarization (RHCP) ensures stable phase center performance and minimizes measurement errors.
High gain with low gain roll-off, enhancing signal reception from low-elevation satellites.
Low-noise, high-gain amplification with excellent out-of-band rejection for strong anti-interference capability.
Compact and lightweight design, making it easy to carry and install.
