Tallysman Introduces VeraPhase 6000 High-Precision GNSS Antenna

Tallysman’s VeraPhase 6000 high-precision GNSS antenna.

Tallysman, a manufacturer of high-performance GNSS antennas, announces the commercial availability of the VeraPhase 6000 antenna series, a family of antennas that provides the lowest axial ratios (horizon to horizon, through all azimuths) across all GNSS frequencies (70 percent), a tight PCV (± 1mm through all frequencies, azimuths, and elevations), and a consistent PCO through all frequencies.

The performance of the VeraPhase rivals that of choke ring antennas, but is much lighter, smaller and more economical, Tallysman said. The antenna family is designed for use in survey, precision RTK and reference antenna applications.

The VeraPhase 6000 also provides an available PCB within the base of the antenna for integration of a custom system board such as a dual-band or RTK GNSS receivers or other applications.

The VP6000 family provides high receive RHCP gain over the full GNSS spectrum:

  • low GNSS band (1164 MHz to 1300 MHz)
  • L-band correction services (1525 MHz to 1559 MHz)
  • high GNSS band (1559 MHz to 1610 MHz).

Each model features a robust, high IP3, pre-filtered LNA to minimize desensing from high-level out-of-band signals, including 700 MHz LTE, and that yet still provides a noise figure of less than 2.5 dB. Non-pre-filtered versions are also available with a noise figure of less than 1.5 dB.

The VP6000 antenna family is available in three formats:

  • A survey-grade all-band antenna that provides 35-dB LNA gain and is available with a robust rubber bumper for field use.
  • An all-band base station antenna is available with 35-dB LNA gain or with an internal 15-dB pre-filtered pre-amp for OEM applications.
  • An all-band reference antenna that features a 50-dB gain LNA, a conical radome to shed snow ice and birds, and is available with a robust monument mount for sub-millimeter precision.

Each antenna has a well defined phase centre offset relative to the antenna reference plane.

The base housing of the VP6000 is IP67-compliant and weighs less than 700 grams. The antenna is 167 millimeters wide at the top, 110 millimeters wide at the base and 110 millimeters in height. Each model has a 5/8-inch x 11 TPI thread for mounting and is available with either a TNC or an N-type connector.

A white paper is available on Tallysman’s website.
