Tallysman, a manufacturer of GNSS antennas and related products that designs and manufactures its products in Ottawa, Canada, announced the introduction of a through-hole mount dual band plus L-Band GNSS antenna: TW3892.

The introduction of this antenna is a continuation of Tallysman’s expansion into broader band GNSS antennas. It employs the company’s Accutenna technology.

The TW3892 can receive GPS L1/L2, GLONASS G1/G2, BeiDou B1, Galileo E1 plus L-band correction services (1213MHz to 1261MHz + 1525MHz to 1610MHz). The antenna has a tight pre-filter to protect against intermodulation and saturation caused by high level cellular 700MHz and other signals, according to the company.

It is designed to provide optimal multi-path signal rejection, a linear phase response, and a tight Phase Centre Variation (PCV), all at an economical price point.

The antenna, which is 66 millimeters by 21 millimeters in mechanical size, is suited for precision agriculture, autonomous vehicles, navigation, RTK, PPP, and other applications where precision matters. The ability of the TW3892 to access L-Band correction services extends its utility to a wider range of applications, the company said.

The TW3892 is housed in a through-hole mount, weather-proof enclosure for permanent installations. For non-rooftop installations, an L Bracket or Pipe Mount (part numbers 23-0040-0, 23- 0065-0 respectively) is available. A 100-millimeter ground plane is recommended for non-roof-top installations.
