Overview

The TW4020/TW4022 is a commercial grade wideband GNSS antenna covering the GPS L1, frequency band. It features a small patch
element with 40% wider bandwidth than typical GPS L1 antennas.

The TW4020/TW4022 features a high performance custom tuned ceramic patch element, 15 KV ESD circuit protection, a high gain two-stage low noise amplifier (LNA) with a mid-section high rejection SAW filter. It covers the GPS L1 and SBAS (WAAS/EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and it offers great circular polarized signal reception.

The TW4022 includes a pre-filter designed to mitigate strong intermodulated or near frequency signals.

Even with the wider bandwidth, the TW4020/TW4022 antenna is among the smallest high performance antenna available. It is housed in a compact IP67 magnetic mount enclosure.
