Tallysman HC600 Iridium Helical Antenna

The HC600 helical antenna from Tallysman supports coverage for Iridium.



The HC600 antenna from Tallysman is a lightweight passive helical antenna covering the Iridium frequency band (1616 MHz to 1626.5 MHz) and is designed to enhance the signal-to-noise ratio of communications over the Iridium voice and data modems.

Weighing 18 g, the lightweight HC600 features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane, making it ideal for a wide variety of applications including Unmanned Aerial Vehicles (UAVs).

The HC600 is protected by a robust, military-grade plastic enclosure with an integrated SMA connector for screw-on mounting that securely seals the unit with an O-ring, complying with IP67 standards. The enclosure also provides two threaded holes in the base for secure attachment of the unit.

An embedded version is also available.
