Overview

Tallysman’s TW8829 is a lightweight compact GPS L1/L2 + GLONASS G1/G2 antenna. This antenna is available either in a housed version (TW8829) or as a OEM (TW1829) antenna. These antennas are ideal for Unmanned Aerial Vehicle (UAV) use because of their low aerodynamic profile and very light weight!

The TW8829 weighs only 52g and is 47.3mm (d) x 18.3mm (h).
The TW1829 weighs only 37g and is 48mm (d) x 12.2mm (h).

The TW8829 features a precision tuned, circular dual feed, stacked patch element as well as a pre-filter. The pre-filter increases the antenna’s immunity to high amplitude interfering signals, such as lTE and other cellular signals.

Applications include airborne Unmanned Autonomous Vehicles, precision GNSS position, dual frequency RTK receivers, mission critical GPS timing, military & security, network timing and synchronization.
