Tallysman launches VeraPhase 6000 GNSS antenna series

Tallysman, a specialist manufacturer of economical high performance GNSS antennas, is pleased to announce the commercial availability of the VeraPhase 6000 antenna Series.

This family of antennas provides the lowest axial ratios (horizon to horizon, through all azimuths) across all GNSS frequencies (<0.5dB at zenith, <2 dB at horizon), great front to back ratios at all elevations, high efficiency (>70%), 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. All these features makes this antenna family ideal for use in survey, precision RTK, and Reference antenna applications.

This antenna 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 (1164MHz to 1300MHz), L-band correction services (1525MHz to 1559MHz), and High GNSS band (1559MHz to 1610 MHz). Each model features a robust, high IP3, pre-filtered LNA to minimize de-sensing from high-level out-of-band signals, including 700MHz LTE, and that yet still provides a noise figure of less than 2.5dB. Non-pre-filtered versions are also available with a noise figure of less than 1.5dB.

The VP6000 antenna family is presently available in three formats:

  • A survey grade all band antenna that provides 35dB LNA gain and is available with a robust rubber bumper for field use.

  • An all-band base station antenna is available with 35dB LNA Gain or with an internal 15dB Pre-filtered pre-amp for OEM applications

  • An all-band reference antenna that features a 50dB Gain LNA, a conical radome to shed snow ice and birds, and is available with a robust monument mount for sub-mm 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 g. The antenna is 167 mm wide at the top, 110mm wide at the base and 110 mm in height. Each model has a 5/8” x 11 TPI thread for mounting and is available with either a TNC or an N-Type connector.

About Tallysman Tallysman is a leading manufacturer of high performance, high quality products for a wide range of Global Navigation Satellite Systems (GNSS) applications. Tallysman’s mission is to provide GNSS antennas which meet the needs of a new generation of positioning systems providing unprecedented accuracy at ever decreasing prices. (www.tallysman.com)

GaN’s Ground-Floor Opportunity
The electronics industry has a major role to play in helping to save energy, by enabling better equipment and new ways of working and living that that are more efficient and environmentally friendly. Maintaining the pace of technological progress is key, but improvements become both smaller and harder to achieve as each technology matures. We can see this trend in the development of power semiconductors, as device designers seek more complex and expensive ways to reduce switching energy and RDS(ON) against silicon’s natural limitations.
