Overview

The TW4327/TW4329 wideband GNSS antenna from Tallysman Wireless uses very little power giving it a very small footprint. It is used for tracking traditional L1 GLONASS, L1 GPS and SBAS signals along the 1575 to 1606 MHz frequency bands.

Although extremely small, it contains a patch element that delivers a bandwidth 40 percent wider than most competitive products. A low-noise amplifier takes approximately 1.75mA of electricity and yet sustains consistent attributes with 2.5V to 16V supply voltages.

Coupled with its extremely low-power consumption is a surprisingly good noise level (21dB nominal gain). The unit also offers a two-stage amplifier and mid-section SAW filter with high-rejection capabilities.

The TW4329 version includes an non-jamming pre-filter. The pre-filter, with its Brick-Wall, eliminates saturation coming from such sources as nearby L-Band signals and/or high-grade sub-harmonics.

Applications include fleet management, asset tracking, security, military and surveillance. This is a magnetic-mount device that meets IP67 standards and operates well in harsh environments.
