Details
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.
