TW3740 Single Band GNSS Antenna 

The TW3740 is a precision high-gain GNSS antenna covering the BeiDou B1, Galileo E1, GPS-L1, GLONASSG1 and SBAS (WAAS, EGNOS, QZSS & MSAS) frequency band (1559 to 1606 MHz).

It employs Calian's patented Accutenna® technology providing truly circular polarized signal reception through the entire bandwidth of the antenna, thereby providing superior multipath signal rejection. It is especially designed for precision timing, industrial, agricultural, military, and other precision applications.

The TW3740 features a three stage low-noise amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage.

The TW3740 is housed in a permanent-mount metal base with two nickel coated nuts and a weatherproof enclosure. Two options for mounting are available: an Lbracket (P/N# 23-0040-0) or a pipe mount (P/N# 230065-0).
