Featuring a precisely tuned, single feed patch element that achieves 40% wider bandwidth than competitive antennas, the TW4020 supports 1 dB RHCP received power across the full frequency. Additionally, the TW4020 has a dual stage Low Noise Amplifier (LNA) with a mid-section SAW that supports a great axial ratio across the full frequency.

The TW4020 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.

LNA Pre-filter Available
