The new antennas have been unveiled at the AUVSI Xponential 2019 tradeshow in Chicago.
The first three models of the Calian 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
The active GNSS helical antennas feature a 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 700MHz band LTE and other near in-band cellular signals.
Available in both housed and embedded OEM versions, the lightweight Calian helical antennas have excellent axial ratios, making them ideal for a variety of high-precision UAV applications.
The housed Calian helical antenna models feature a robust, military-grade plastic case, while the embedded Calian 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.
“There is a clear requirement for lightweight, high performance antennas for the rapidly growing UAV market. These new patented helical products are an extension to our existing range of superlight L1/L2 patch antennas, and will provide customers with a wider choice of antenna formats to suit their specific application requirements”, says Calian’s President and CTO, Gyles Panther. “These are the first of a number of new products we plan to introduce for this application to support our already wide customer base for UAV antennas.”
