The TW4421 is a high-performance, dual-feed GNSS antenna providing coverage for GPS L1 and GLONASS L1. It features a high-grade dual-feed patch element that provides excellent axial ratio and tight phase center variation. The antenna includes a low-noise amplifier (LNA) with integrated high-rejection filters to minimize interference from non-GNSS signals. The housing is industrial grade, waterproof (IP67), and features a magnetic mount for easy installation on metallic surfaces.
