The TW4027/TW4029 by Tallysman Wireless is a professional type of GNSS antenna. It operates on the frequency band for L1 GPS signals using very low power. Its low-noise amplifier requires only 2mA of minimal electricity, yet it delivers constant operations with supply voltage ranging from 2.5V to 15V. It also eliminates disturbances from Globalstar and Iridium L-Band antennas transmitting nearby.
Despite its amazing low-power consumption, noise level is excellent and nominal gain measures 21dB. Axial ratio is enhanced by 40 percent wider bandwidth than comparable units; 15 KV ESD circuit protection is provided.
Operating with a bandwidth of approximately 10MH, it tracks traditional L1 GPS and SBAS signals. TW4029 is an optional version with a “Brick-Wall” pre-filter, which eliminates saturation originating from high-level sub-harmonics as well as L-Band signals.
TW4027/TW4029 comes with three meters of cable, a variety of SMA connectors and an IP67-rated magnetic-mount enclosure.
