TW4027/TW4029 Low Current GPS Antenna  
The TW4027/TW4029 is a very low power,  
compact GNSS antenna covering the GPS L1,  
frequency band. This antenna features an LNA  
with a nominal current consumption of just  
2mA, with constant performance from 2.5V to  
15V supply voltage, and includes protection  
against close proximity L-band transmitting  
antennas such as Iridium™ and Globalstar™  
The TW4027/TW4029 has among the lowest  
power consumption available, yet still provides  
21dB nominal gain and an excellent Noise  
Figure. The TW4027.TW4029 patch has 40%  
wider bandwidth for better axial ratio and has  
15 KV ESD circuit protection. The LNA has a  
+/- 10MHz bandwidth that covers the full GPS  
L1 signal plus the SBAS (WAAS /EGNOS/MSAS)  
frequency band (1572.5 to 1578 MHz).  
The TW4029 variant provides a “Brick-Wall”  
pre-filter to protect against saturation by high  
level sub-harmonics and L-Band signals.  
It is housed in a compact IP67 magnetic mount  
enclosure.  
Applications  
Battery operated monitoring  
Covert Surveillance  
Fleet Management & Asset Tracking  
Satcom based AVL solutions
