With global headquarters and manufacturing in Ottawa, Canada, Tallysman is a leading manufacturer of high-precision antennas and components for Global Navigation Satellite Systems (GNSS) applications. Tallysman’s mission is to support the needs of a new generation of positioning systems by delivering unprecedented antenna precision at competitive prices. Additionally, Tallysman has a line of choke ring amplifiers to upgrade your existing choke rings to receive all of the GNSS signals.


  • VeraPhase Antennas
    Tallysman`s patented VeraPhase® technology introduces extremely high performance in a light weight package. It provides the lowest axial ratios from horizon to horizon, has a very low current draw, and is easy to install....

  • The patented VeraPhase® 6000 antenna is a full GNSSspectrum antenna plus L-band correction services.  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, <2 dB typ. at horizon).  It has an exceptional front to back ratios, high efficiency (>70%), a tight PCV, and near constant PCO for all azimuth and elevation angles, over all in-band frequencies.  The performance of the VeraPhase® rivals any geodetic / reference antennas including choke ring antennas but is lighter, smaller, more economical, and requires less power.  The antenna has been calibrated by GEO++ and the type mean calibration files are available in the IGS and NGS databases.

    The VP6000 provides high receive gain over the full GNSS spectrum: Low GNSS band (1164MHz to 1300MHz) L-band correction services (1525MHz to 1559MHz) 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 noise figure of less than 2.0dB.

    It is available with either a flat or a conical radome.  It is currently operating in the IGS network.
