Tallysman HC871 Dual Band Helical Antenna

Ideal for a wide variety of applications including Unmanned Aerial Vehicles (UAVs), the lightweight HC871 weighs only 25 g and features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane.

The HC871 features an industry-leading low current, Low Noise Amplifier (LNA) that includes an integrated low-loss pre-filter to protect against harmonic interference from high amplitude interfering signals, such as 700 MHz band LTE and other near in-band cellular signals.

The HC871 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 three threaded holes in the base for secure attachment of the unit.
