Lightweight Helical GNSS and Iridium Antennas for the UAV Market

1556728438175_636923252529179127Tallysman has introduced the first three products of a new range of helical antennas to be introduced in 2019. These active GNSS helical antennas feature low current, Low Noise Amplifier (LNA), and include integrated low-loss pre-filters, to protect against harmonic interference from high amplitude interfering signals, such as 700 MHz band LTE and other near in-band cellular signals.

The first three models of the Tallysman helical family are:

HC871 (25g) – A housed, dual-band, active GNSS antenna, supporting GPS L1/L2, GLONASS G1/G2, Galileo E1, and BeiDou B1.

HC872 (36g) – A housed, dual-band, active GNSS antenna, supporting GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1, and L-Band services.

• HC600 (18g) – A housed, passive Iridium antenna.

Available in both housed and embedded OEM versions, the lightweight Tallysman helical antennas have excellent axial ratios, making them ideal for a variety of high-precision Unmanned Aerial Vehicle (UAV) applications.

The housed Tallysman helical antenna models feature a robust, military-grade plastic case, while the embedded Tallysman helical antenna models can be custom-tuned for any application and configured with a variety of cables and connectors. Patents have been applied for with respect to several aspects of these new products.
