Tallysman Wireless wideband GNSS antenna TW4327/TW4329 uses very little power despite its small footprint. It is used for tracking traditional L1 GLONASS, L1 GPS and SBAS signals along the 1575 to 1606 MHz frequency bands.
Although extremely small, it contains a patch element that delivers a bandwidth 40 percent wider than most competitive products. A low-noise amplifier takes approximately 1.75mA of electricity and yet sustains consistent attributes with 2.5V to 16V supply voltages.
Coupled with its extremely low-power consumption is a surprisingly good noise level (21dB nominal gain). The also unit offers a two-stage amplifier and mid-section SAW filter with high-rejection capabilities.
The optional TW4329 version includes an non-jamming pre-filter. The pre-filter, with its
