TW4020/TW4022 Wideband GPS Antenna

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

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.
