Tallysman TW3430/TW3432 Timing Antennas
This product was replaced by the TW3400/TW3402.
The TW3430/TW3432 are professional grade GNSS antennas covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). They are especially designed for precision timing applications and offer excellent circular polarized signal reception, multipath rejection and out of band signal rejection.
Â
The TW3430/TW3432 feature a highly circular dual-feed wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per feed, a mid-section combining circuit and SAW. This configuration provides an excellent axial ratio that is constant across the full frequency band. An optional tight pre-filter is available with part number TW3432 to protect against saturation by high level sub-harmonics and L-Band signals.
Â
The TW3430/TW3432 are housed in a permanent mount industrial-grade weather- proof enclosures with a conical shaped radome, and a TNC Jack (female) connector.
