28 dB typ.
Many Options, Please Inquire
The TW1721 is a compact, wideband GNSS antenna employing patented Accutenna® technology, providing accurate reception for all upper-band GPS/QZSS-L1, GLONASS-G1, Galileo-E1, and Beidou-B1 signals, and associated augmentation signals (WAAS, EGNOS and MSAS).
- Compact dual-feed patch element
- Low noise LNA: <1.0 dB
- Axial ratio: 2.0 dB typ. over the full bandwidth
- LNA gain: 28 dB typ.
- Wide voltage input range: 1.8 to 16 VDC
- ESD circuit protection: 15KV
- Temperature-compensated gain
- RoHS and REACH compliant
- Great multipath rejection
- Great out-of-band signal rejection
- High system accuracy
- Improved carrier phase linearity
- Excellent signal-to-noise ratio
- Compact form factor
- Reliable performance
Ideal for applications that require high precision positioning and timing in a small form factor, the TW1721 provides superior multi-path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV).
Featuring a compact 25mm dual-feed wideband patch element, the TW1721 provides a truly circularly polarized response, with a typical axial ratio of less than 2dB over the full bandwidth.
Tallysman offers custom tuning services to optimize the performance of the TW1721 for any OEM installation environment.
LNA Pre-filter Available
If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, the alternative TW1722 provides these additional benefits with an LNA pre-filter. Click here to learn more about the TW1722.
