Tallysman TW3470/TW3472 GPS/GLONASS Timing Antenna

The TW3470/TW3472 from Tallysman Wireless are professional grade 40dB fixed mount Timing antennas covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz).



The TW3470/TW3472 GPS/GLONASS timing antennas are especially designed for timing, precision and military applications and offer excellent circular polarized signal reception, multipath rejection and out of band signal rejection.

They feature a highly circular dual-feed wideband patch element, with a three stage Low Noise Amplifier. This configuration provides excellent axial ratio that is constant across the full frequency band. An optional tight pre-filter is available to protect against saturation by high level sub-harmonics and L- Band signals with part number TW3472.

The TW3470/TW3472 are housed in a permanent mount industrial-grade weather- proof enclosure, and comes with a TNC Jack (female) connector.
