Tallysman’s TW4327/TW4329 is a small GNSS wideband antenna that consumes very little power. It is employed on the 1575 to 1606 MHz frequency bands to cover GLONASS L1, GPS L1 and SBAS (including EGNOS, MSAS, WAAS) signals.
Compared to most of the competition, this antenna’s patch element has a 40 percent wider bandwidth. At the same time it is smaller than others.
Typically, current use is only 1.75 mA. Supply voltages
range from 2.5V to 16V. The low noise amplifier comes with a high-rejection mid-section SAW. An anti-jamming pre-filter is available optionally as TW4329.
Even though the TW4327/TW4329 require less power than competitive units, the TW4327 still delivers a great noise figure (21dB nominal gain).
The TW4329 variant provides a “Brick-Wall” pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.
The TW4327/TW4329 are housed in a compact, magnetic mount, IP67 compliant housings. It is RoHS and REACH compliant.
Applications include fleet management, asset tracking, covert surveillance, military, security and battery operated mission critical positioning
