LNA upgrades enable expanded GNSS reception
Tallysman, a manufacturer of high-performance GNSS antennas, has released a family of high-performing economical wideband low noise amplifiers (LNAs) for choke-ring antennas.
Tallysman offers four models of the LNA with options of 35-dB and 50-dB gain. The capabilities of the models are shown in the table below. The LNAs are designed for upgrading existing choke-ring antennas with Dorne Margolin/EDO elements to receive new and expanding GNSS signals.
The LNAs provide consistent gain across the full bandwidth and include filters for suppression of out-of-band interfering signals, such as cellular LTE and Iridium signals, while maintaining a low noise figure, high third-order intercept point, small group delay and low power consumption, the company said.
The enclosure is designed to fit a wide variety of currently deployed choke-ring antennas.
