## A Tallysman _Accutenna[®]_ 

## TW3710P Passive Multi-Constellation Fixed Mount Antenna 

The TW3710P is a passive antenna built on 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). 

The TW3710P features a precision tuned, dual feed, circular patch element.  The signals from the two orthogonal feeds are combined in phase quadrature in a hybrid combiner to provide a mathematically correct transfer function for a RHCP signal. 

The TW3710P offers excellent axial ratio and a tightly grouped phase center variation. 

The TW3710P is housed in a through-hole mount, weather-proof enclosure for permanent installations.  L Bracket or Pipe Mount (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation.
