TW3740 / TW3742 Dual Feed Multi-Constellation Timing Antenna
The TW3740 and TW3742 multi-constellation GNSS timing antennas are precision high-gain GNSS antennas covering the BeiDou B1, Galileo E1, GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS, QZSS & MSAS) frequency band (1557 to 1606 MHz).
These antennas employ Tallysmans unique Accutenna™ technology to provide truly circular polarized signal reception through the entire bandwidth of the antenna for superior multipath signal rejection. 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. An optional tight pre-filter is available on the TW3742 to protect against saturation by high level sub-harmonic and L-Band signals.
The TW3740/TW3742 is housed in a permanent mount metal base with two nickel coated nuts and a weather-proof enclosure. Two options for mounting are available: an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).
The TW3740 and TW3742 are especially designed for precision timing, industrial, agricultural, military, and other precision applications.
