A Tallysman Accutenna®
TW3710 /TW3712 Multi-Constellation Fixed Mount Antenna
The TW3710 /TW3712 employs Tallysman’s uniqueAccutenna® 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 especiallysuitable for high accuracy applications, and also offers highout 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.

TW3710 / TW3712 Dimensions (mm)

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, weatherproof 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.

A Tallysman Accutenna®
TW3870 / TW3872 GPS L1/L2 + GLONASS G1/G2 + BeiDou B1 + Galileo E1
The TW3870/ TW3872 employ Tallysman’s unique Accutenna
technology providing dual band GPS L1/L2, GLONASS G1/G2 +BeiDou B1 + Galileo E1 coverage and is especially designed for
precision dual frequency positioning.
The TW3870/TW3872 features a precision tuned, circular dual
feed, stacked patch element. The signals from the two orthogonal
feeds are combined in a hybrid combiner, amplified in a wide-band
LNA, then band-split for narrow filtering in each band and further
amplified prior to recombination at the output.
The TW3870/TW3872 offers excellent axial ratio and a tightly
grouped phase center variation.
The TW3870/TW3872 covers GPS L2 (1227.6MHz), GLONASS G2(1248MHz centre), GPS L1/WAAS/EGNOS/MSAS (1575.42MHz),GLONASS G1 (1602MHz, centre), BeiDou B1 and Galileo E1. (1561and 1589 MHz).

TW3870 Dimensions (mm)

The TW3872 has a pre-filter which increases the antenna’s
immunity to high amplitude interfering signals, such as LTE andother cellular signals.
The TW3870/TW3872 is housed in a through-hole mount,weather-proof enclosure for permanent installations. L Bracket orPipe Mount (part numbers 23-0040-0, 23-0065-0 respectively) areavailable for non-rooftop installation. A 100mm ground plane isrecommended for non-roof-top installations.
This product is also available in an OEM formats (TW3865,TW3870E, TW3872E, and TW3868)
