    The design will offer simultaneous GNSS reception on L1: GPS, GLONASS, Galileo, Beidou, L2: GPS L2C, Galileo E5B, and GLONASS L3OC, and L5: GPS + L-band corrections in a rugged, compact, and ultra-lightweight form factor. The antenna is well suited for high precision applications. The M9HCT-A-SMA is a great fit for the UAV markets, where high performance and low weight are driving features in antenna selection.

    The new rugged active helix antenna is designed and manufactured using automotive grade electronics for GIS, RTK and other GNSS applications.

    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.
