Tallysman TW3752 Single Band GNSS Antenna
The TW3752 is a single band GNSS antenna from Tallysman, covering GPS/QZSS L1, GLONASS G1, Galileo E1, BeiDou B1, as well as SBAS (WAAS/EGNOS/MSAS).
Ideal for high-density, telecommunications tower timing applications, where high levels of near-out-of-band interfering signals are common, the TW3752 is designed to provide strong circular polarized signal reception, multi-path and out-of-band signal rejection. Additionally, with a high gain Low Noise Amplifier (LNA) of 50 dB, the antenna is able to support long cable runs often necessary for tower installation.
The TW3752 features a customizable dual-feed, wide-band patch element, with a three-stage Low Noise Amplifier, and provides an axial ratio that is constant across the full frequency and tight phase centre variation.
The TW3752 features an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.
