Tallysman TW3320/TW3322 Wideband GPS/GLONASS Antenna

Description

Overview

The Tallysman TW3320/3322 is a high performance GNSS antenna covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1575 to 1606 MHz). It features a patch element with 40% wider bandwidth than hitherto available in this format. Unlike its competitors, both GPS-L1 and GLONASS signals are included in the 1dB received power bandwidth.

The TW3320/TW3322 has a two stage Low Noise Amplifier with a mid-section SAW. An optional tight pre-filter is available with part number TW3322 to protect against saturation by high level sub-harmonics and L-Band signals.

The TW3320/3322 has a 19mm (3/4 Inch) though-hole mount white metal base, specifically designed for mobile installations, with an industrial-grade, IP67 compliant conical radome. The standard connector is a TNC Jack (female).
