HC610 Active Iridium Helical Antenna
Surface Mount / Direct Screw
28 dB typ.
Weighing only 24 g, the patented light and compact HC610 features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane. It is designed to receive Iridium Satellite Time and Location (STL) signals, used by STL terminals to provide worldwide position, navigation, and timing independent of GPS/GNSS, via a secure encrypted satellite broadcast signal that is strong enough for indoor reception.
- LNA gain (28 dB typ.)
- Excellent axial ratio (≤ 0.5 dB at zenith)
- ESD circuit protection (15 kV)
- Supports long cable runs
- Robust industrial-grade enclosure
- IP67, REACH, and RoHS compliant
- Extremely lightweight (24 g)
- Excellent RH circular polarized signal reception
- Increased system accuracy
- Excellent signal-to-noise ratio
- Industrial temperature range
- Rugged design, ideal for harsh environments
- Remote SBD antenna
Since GNSS signals may be jammed (intentionally or accidentally) and spoofed, STL signals are a reliable alternative to augment and authenticate time for applications, such as electrical grids, wireless communications networks, and financial systems, as well as position for private and public infrastructure.
The HC610 is an active Iridium antenna that operates in receive-only mode and enables Iridium terminals to be installed tens of metres away from the antenna. It also features a low-current, low-noise amplifier (LNA) and pre-filter to prevent harmonic interference from high-amplitude signals, such as 700 MHz band LTE and other nearby in-band cellular signals.
All Tallysman housed helical antenna elements are protected by a robust military-grade IP67-compliant plastic enclosure. The enclosure’s base provides two threaded inserts for secure attachment, as well as a rubber O-ring around the outer edge to seal the antenna base and its integrated male SMA connector.
Tallysman®’s HC610 has passed a rigorous 30-hour vibration test procedure, consisting of five cycles of 2-hour tests per axis (x, y, z):
___• Cycle 1: 1.05 Grms;
___• Cycle 2: 1.20 Grms;
___• Cycle 3: 1.35 Grms;
___• Cycle 4: 3.67 Grms;
___• Cycle 5: 3.67 Grms.
