A Tallysman Accutenna^®

TW4421/TW4422 Wideband Dual Feed GPS/GLONASS Antenna

The TW4421/TW4422 employs Tallysman’s

patented

Accutenna^®technology covering the GPS L1, GLONASS G1, and

SBAS (WAAS, EGNOS & MSAS) frequency band (1574 to 1606

MHz). The TW4421/TW4422 features a novel 25mm dual feed

wideband patch element that provides a more linear carrier

phase response by virtue of the axial ratio that is greatly

improved across the full frequency bandwidth. It provides truly

circular response over its entire bandwidth thereby producing

superior multipath signal rejection. It is especially suitable for

high accuracy applications while providing high out of band

signal rejection.

The two feeds from the patch element are summed in a 90°

Hybrid then input to a first stage Low Noise Amplifier (LNA),

followed by a mid-section SAW and a second low noise gain stage.

The TW4422 has a pre-filter which increases the antenna’s

immunity to high amplitude interfering signals, such as LTE and

other cellular signals

The TW4421/TW4422 is the smallest dual feed, high

performance antenna available. It is housed in a compact IP67

magnetic or adhesive mount enclosure. It is available with a wide

range of cable and connector options.

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 doublesided VHB tape on the bottom.
