Tallysman TW1421 Benefits from:
Great multipath rejection
Increase system accuracy
Improved carrier phase linearity
Excellent signal to noise ratio
Great out of band signal rejection
Compact form factor
RoHS compliant

The TW1421 features a compact 25mm dual feed, wideband patch element and a Low Noise Amplifier (LNA). As a result it supports a great axial ratio and cross polarisation rejection across the full frequency supported by the antenna.

Ideal for applications that require high precision positioning and timing in a small form factor, the TW1421 provides superior multi path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV).

Custom Tuning
Tallysman offers custom tuning services to optimise the performance of the TW1421 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 TW1422 provides these additional benefits with an LNA pre filter.
