The VeraChoke 6100 antenna offers a choice in form-factor for reference and monitoring applications, while also delivering the best performance of any choke ring antenna available on the market. The patented VeraChoke 6100 antenna is a full GNSS spectrum antenna. 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, overall azimuths) across all GNSS frequencies (<0.5dB at zenith, <3 dB typ. at horizon). It has an exceptional front to back ratios, high efficiency (>80%), a tight PCV, and near-constant PCO for all azimuth and elevation angles, overall in-band frequencies.

The VC6100 provides high receive gain over the full GNSS spectrum: Low GNSS band (1164MHz to 1300MHz) and High GNSS band (1559MHz to 1610 MHz). It has a robust pre-filtered LNA, with high IP3 to minimize de-sensing from high-level out-of-band signals, including 700MHz LTE, while still providing a low noise figure.

The antenna is compatible with both large and small SCIGN radomes.

  • Low axial ratios from horizon to horizon
