Tallysman TW3712 Fixed Mount Pre-Filtered GNSS GPS Antenna TNC-Female

Description

This is a brand new Tallysman TW 3712 antenna with a female TNC connector and the low profile white dome option.
The exact model number is 33-3712-01-11
The 33-3712 is the antenna type number, -01 is for a female TNC connector, and the -11 is because it’s the low profile white flat dome.
It has all the included fittings which are the weatherproof gasket, metal washer, two nuts, and the antenna connector cover for when it’s not in use or being transported.

Details
Ideal for high-accuracy applications the TW3712 provides truly circular response over its entire bandwidth thereby producing excellent multi-path and out-of-band signal rejection.
TW3712 antennas features a dual-feed wide-band patch element, with a two stage Low Noise Amplifier (LNA), comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage.
Providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, The TW3712 also includes an LNA pre-filter.
The TW3712 provides excellent axial ratio that is constant across the full frequency band along with a superb phase linear response and tight phase centre variation.
The TW3712 employs Tallysman’s unique Accutenna® technology covering the BeiDou B1, Galileo E1, GPS L1, GLONASS G1 and SBAS (WAAS, QZSS, EGNOS & MSAS) frequency band (1557 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. It is especially suitable for high accuracy applications, and also offers high out of band signal rejection.
Both antennas feature a dual-feed wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage. This configuration provides excellent axial ratio that is constant across the full frequency band along with a superb phase linear response and tight phase centre variation providing performance normally associated with much higher priced antennas.
The TW3712 has a pre-filter to protect against front end saturation by strong near frequency or harmonic signals.
The antennas are housed in a through-hole mount, weather- proof enclosure for permanent installations. L Bracket or Pipe Mount adapters (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation. A 100mm ground plane is recommended for non-roof-top installations.
