TW3442 Single Band GNSS Antenna (Pre-filtered)

The TW3442 employs Calian's patented Accutenna® technology, covering the GPS-L1, GLONASS-G1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1575 to 1606 MHz). They are especially designed for timing, mobile, precision, safety and security applications. They provide truly circular response over the antenna’s entire bandwidth thereby producing superior multipath signal rejection.

The TW3442 each feature a highly circular dual-feed wideband patch element, with a three stage low-noise amplifier. This configuration provides excellent axial ratio that is constant across the full frequency band. TW3442 is a tight pre-filter protects against saturation by high-level sub-harmonics and L-Band signals.

The TW3442 is housed in a permanent-mount industrialgrade weatherproof enclosure, and is available with a wide variety of connectors.

The antenna is available with either a flat or a conical radome. Conical radomes are recommended for permanent locations to ward off birds and shed ice/snow.
