Tallysman TW3870E Antenna
The TW3870E Cover GPS L1/L2 GLONASS G1/G2 Galileo E1 BeiDou B1 Frequency Bands
The Tallysman TW3870E employs Tallysmans unique Accutenna™ technology which provides truly circular response over the entire bandwidth thereby producing multipath signal rejection resulting in higher positional and timing accuracy. The TW3870E covers the GPS L1/L2, GLONASS G1/G2, and SBAS (WAAS, EGNOS & MSAS) frequency bands. The TW3870E offers excellent axial ratio and a tightly grouped phase center.
- Accutenna™ Technology
- Tight Phase Center Variation (PCV)
- Low noise LNA: 2dB max.
- Temperature compensating LNAs
- Superior multipath signal rejection
- Ideal for RTK and PPP applications
- Excellent signal-to-noise ratio
- Consistent response in all operating temperatures
The OEM TW3870E is supplied with a standard 60mm diameter circular ground plane, with a coaxial cable terminated with a connector. Mounting holes are provided for attachment to larger ground planes.
The TW3870E is REACH and RoHS compliant.
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 TW3872E provides these additional benefits with an LNA pre-filter.
To minimize performance impact from signal jamming threats, the pre-filtered version of this antenna is compatible with Tallysman’s Anti-Jamming add-on, which modifies the radiation pattern of the GNSS antenna to eliminate signals arriving from -10° to +15° from horizon, while slightly increasing the gain of the antenna at zenith.
