SKU: 33-4037 Categories: , Manufacturer: Tallysman Wireless

Tallysman TW4037 Single Band GNSS Antenna

The TW4037 requires very low power of just 5.5 mA with constant characteristics over supply voltages from 2.5V to 16V .   It is ideal for battery operated positioning and fleet management and asset tracking applications. This single-feed patch element achieves a very wide bandwidth compared to other competitive antennas. It supports 1 dB RHCP received power across the full frequency. The TW4037 has a dual stage Low Noise Amplifier (LNA) with a mid-section SAW that supports a great axial ratio across the full frequency. The TW4037 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.

LNA Pre-filter Available
If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, the alternative TW4039 provides these additional benefits with an LNA pre-filter.
