Ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where antenna precision matters, the TW2920 provides superior multi-path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV).
The TW2920 features a dual-feed wideband patch element and a low-loss pre-filter, followed by a three stage Low Noise Amplifier (LNA) that includes an additional mid-section Surface Acoustic Wave (SAW) filter. This configuration provides excellent axial ratio across the full frequency band and strong protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.
The TW2920 has a compact, a UV resistant plastic radome housing with a tough wide temperature range and has metal base can be surface mounted via screws, adhesive or magnets. The TW2920 is available with a variety of connectors and cable length can be customized up to 5m.
The TW2920 is also available with an ‘armoured’ cable option, where the cable is encased in tough corrugated conduit that withstands a temperature range of -40 to +120C, has excellent chemical resistance, is stable against bending, has high cold impact strength, and is UL94HB flammability standard compliant.
