Tallysman Wireless Inc., an Ottowa-based provider of high-performance RF and GPS/GNSS components and telematics products, has relesed six permanent-mount GPS/GNSS antennas.

The TW3000 series antennas are professional-grade, permanent-mount GPS and GPS+GLONASS antennas are designed for professional tracking and timing applications. The antennas feature custom high-performance, wide-band single- or dual-feed precision-grade patch elements, 28 dB or 40 dB gain LNAs, and high rejection out-of-band SAW filters. According to Tallysman, they provide great axial ratio, excellent circular polarized signal reception, great multipath rejection, and great out-of-band signal rejection.

The TW3000 series antennas are housed in a permanent-mount industrial-grade weatherproof enclosure. They come with low profile radome for tracking applications or a conical radome for timing applications, and a TNC Jack (female) connector.

Tracking antennas with low profile dark gray radome include:
TW3040 – 40dB gain GPS L1, single-feed patch
TW3100 – 30dB Precision grade GPS L1, dual feed patch
