Overview

Tallysman Wireless’ TW3802 dual-feed, dual-band antenna receives both GLONASS G1/G2 and GPS L1/L2 signals. It is specifically designed for very precise dual-band positioning.

The antenna has a patch element that is precision tuned and circularly stacked with dual feeds. Both orthogonal feeds are united in a hybrid combiner. A duplexer band-splits the resulting signal for pre-filtering before being amplified in individual low noise amplifiers designated for each band.

The unit also provides a narrowly grouped phase center above elevation angles from zenith to 0 horizon degrees.

TW3802 is enclosed in a permanent-mount and industrial-grade weatherproof radome. There are two options for mounting on poles.

Applications include GPS precision position, RTK dual-frequency receivers, GPS mission critical timing, military and security, network synchronization and timing.
