Many Options, Please Inquire
The TW3440 employs Tallysman’s unique Accutenna® technology, covering GPS/QZSS L1, GLONASS G1, as well as SBAS (WAAS, QZSS, EGNOS & MSAS).
- Great axial ratio: 1 dB typ.
- High gain LNA: 39 dB
- Low noise LNA: 1dB typ.
- Low current: 19 mA typ.
- Wide supply voltage: 2.5 to 16 VDC
- IP69K, RoHS and REACH compliant
- Available conical radome
- Excellent circular polarisation
- Long Cable Runs
- Excellent signal to noise ratio
- Excellent multipath rejection
- Increased system accuracy
- Ideal for harsh environments
Ideal for timing, mobile, precision and all challenging applications the TW3440 provides truly circular response over its entire bandwidth thereby producing excellent multi-path and out-of-band signal rejection.
TW3440 antenna features a dual-feed wide-band patch element, with a three-stage Low Noise Amplifier (LNA), and provides an excellent axial ratio that is constant across the full frequency, superb phase linear response and tight phase centre variation.
The TW3440 is housed in a permanent mount industrial grade weather-proof enclosure, available in conical or flat radome styles and in grey or white colours. Two options for pole mounting are available an L-Bracket or a Pipe Mount. A 100mm ground plane is recommended for non-roof-top installations.
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 TW3402 provides these additional benefits with an LNA pre-filter. Click here to learn more about the TW3442.
