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.
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.
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.
