Tallysman’s HC977XF Benefits from:
Extremely lightweight (42 g)
Ideal for L1 / L2 / L5, E1 / E5a / E5b RTK surveying systems
Great multipath rejection
Increased system accuracy
Excellent signal to noise ratio

HC977XF, 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.

Tallysman‘s HC977XF 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.

HC977XF 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.

Tallysman’s eXtended Filter (XF) antenna technology has been designed to mitigate out of band signals and prevent GNSS antenna saturation.
