Tallysman Upper GNSS Band + L-Band capable antennas


The TW2920 antenna provides simultaneous reception of L-band correction signals and all of the upper band GNSS signals including GPS L1, GLONASS G1, Galileo E1, and BeiDou B1. The TW2920 1dB bandwidth covers 1525MHz to 1559MHz for the L band down-link and 1559MHz to 1610MHz for the upper band GNSS.

These antennas are ideal for use in precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.

The TW2920 provides LNA of 28dB of gain and the TW2940 is available with a higher gain of 35dB LNA.  The TW2920 and TW2940 have metal bases with wide temperature range plastic radomes, 57mm in diameter and 15mm in height, with a magnetic mount or adhesive mount along with four tapped screw holes. They are IP67 compliant and available with either a watertight SMA connector on the bulkhead or with a RG174 cable with your choice of connector.

With Tallysman’s Accutenna™ technology, the TW2920 / TW2040 have proven ability to provide strong cross-polarization rejection for greatly improved multi-path rejection, low axial ratio, and tight Phase Center Variation (PCV). These antennas are smaller, lighter, and less expensive than similarly capable antennas on the market, without compromising performance.

An OEM variant is also available – the TW2926 antenna is an unhoused OEM version of the TW2920 with 28dB of gain.

All of these antennas include a sharp pre-filter to protect against sub-harmonic signals such 700MHz LTE and strong near frequency signals such as WiFi.
