Overview

Tallysman’s TW7872 provides a range of benefits to its users. Along with offering impressive multipath rejection, the antenna also provides a great signal to noise ratio and increased system accuracy. This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision is a top priority.

The TW7872 features a precision-tuned, twin circular dual feed, stacked patch element. Both signals from the orthogonal feeds are merged in a hybrid combiner, pre-filtered to minimize interference from out of band signals (cellular LTE) then amplified in a wide-band LNA and band-split for additional filtering and amplification stages prior to recombination at the output.
