A Tallysman Accutenna^®

TW4721/TW4722 Wideband Dual Feed GPS/GLONASS/BeiDou/Galileo Antenna

The TW4721/TW4722 is a compact, wideband GNSS antenna

that provides accurate reception for all upper L- band GPS,

GLONASS, Beidou, and Galileo signals ( L1, G1, B1, B1 BOC,

B1-2, E1) and associated augmentation signals (WAAS,

EGNOS and MSAS SBAS).

This antenna employs

Tallysman’s patented Accutenna technology.

The TW4721/TW4722 features a novel 25mm dual feed

wideband patch element that, in sharp contrast with its

competitors, provides a truly circularly polarized response, with

a typical axial ratio of less than 2dB over the full bandwidth.

This provides a more linear carrier phase response and

substantially improved multipath rejection for higher precision

applications.

The TW4722 is the pre-filtered version of the TW1721. The

pre-filter provides protection from near frequency or strong

harmonic interfering signals.

The TW4721/TW4722 is the smallest, lightest, wideband GNSS

antenna available. It is housing in a compact IP67 magnetic or

adhesive mount enclosure and is available with a wide range of

connector options and custom coax cable lengths.

The antenna can be ordered without the magnet. In such cases,

the magnet is replaced with a plastic plug to provide a smooth

under surface, with the option of ordering it with or without 1.1

mm double-sided VHB tape on the bottom.
