Details

The Tallysman HC977 is light weight (Just 42 g) and compact. It features a precision tuned helix element. As a result it provides excellent axial ratios while operating without the need of a ground plane. It is ideal for a variety of uses such as UAVs.

The HC977 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 HC977 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.
