A Tallysman Accutenna^®

TW3740 / TW3742 High Gain Multi-Constellation Antenna

The TW3740 / TW3742 is a precision high gain GNSS

antenna covering the BeiDou B1, Galileo E1, GPS L1,

GLONASS L1 and SBAS (WAAS, EGNOS, QZSS & MSAS)

frequency band (1557 to 1606 MHz). It employs

Tallysman’s unique 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.

Conical radome pictured here. Flat radome also available. Also

available in White

The TW3742 adds an additional pre-filter to provide

extra strong protection from near frequency and strong

harmonic 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).
