VeraChoke™ 6100 AntennaHigh Precision Full GNSS Spectrum Choke Ring Antenna
The patented VeraChoke 6100 antenna is a full GNSS spectrumantenna. It has consistent performance (gain, axial ratio, PCV,and PCO) across the full bandwidth of the antenna. It provides
the lowest axial ratios (horizon to horizon, over all azimuths)
across all GNSS frequencies (<0.5dB at zenith, <3 dB typ. athorizon). It has an exceptional front to back ratios, high efficiency(>80%), a tight PCV, and near constant PCO for all azimuth andelevation angles, over all in-band frequencies.
The VC6100 provides high receive gain over the full GNSS
spectrum: Low GNSS band (1164MHz to 1300MHz) and HighGNSS band (1559MHz to 1610 MHz). It has a robust pre-filtered
LNA, with high IP3 to minimize de-sensing from high-level outof-band signals, including 700MHz LTE, while still providing alow noise figure.
The antenna is compatible with both large and small SCIGN
radomes.
Other models are available with different reception capabilities.
