Overview

Tallysman Wireless’ TW3805 is a dual-band, dual-feed OEM antenna for GLONASS G1/G2 and GPS L1/L2 signal reception. It is conceived of for high precision, dual-band positioning purposes.

Dual feed is provided by a circular, stacked patch element that is tuned to high precision. The two feeds, which are orthogonal, are coupled in a hybrid blender and the output signal is split by a diplexer for pre-filtering before being amplified in isolated low-noise devices for the dual bands.

TW3805 has its closely bundled phase center over zenith to 0 degrees horizon elevation angles.

The OEM unit comes with a ground plane that is circular. The end of its coaxial cable is provided with a connector (right-angle MCX). There are holes for mounting to bigger ground planes. Manufacturer can provide custom tuning and/or ground plane options depending on the number of units purchased.

Applications include anti-jamming and mission-critical GPS as well as surveying systems, network timing and synchronization and military and security purposes.
