Tallysman TW1422 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
The TW1422 features a compact 25mm dual feed, wideband patch element and a two stage 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 TW1422 provides superior multi path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV).
Tallysman offers custom tuning services to optimise the performance of the TW1422 for any OEM installation environment.
The non prefiltered version is the TW1421
