TW3865 Embedded GPS L1L2 GLONASS G1G2 Antenna

 
This dual band GPS L1 & L2 and GLONASS G1 & G2 antenna by Tallysman is designed for precision dual-frequency positioning. It is ideal for dual frequency Precise Point Positioning (PPP) systems.
 
The TW3865 features a precision tuned, circular dual feed, stacked patch elements. Signals from 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. This provides truly circular response over the entire bandwidth of the antenna.
 
The TW3865 offers excellent axial ratio and a tightly grouped phase center. The TW3865 covers GPS L2 (1227.6MHz), GLONASS G2 (1248MHz centre), GPS L1/WAAS/EGNOS/MSAS (1575.42MHz) and GLONASS G1 (1602MHz, centre).
 
The OEM TW3865 comes with a standard 60mm diameter circular ground plane and a coaxial cable terminated with a connector (right angle MCX is shown in the drawing). Mounting holes are provided for attachment to larger ground planes.
 
Custom tuning and ground plane options may be available, depending on purchase level commitment.
