HC3990XF

Overview

The HC3990XF eXtended-Filter Low-Profile Helical Antenna, integrated into the TW3000 base, delivers exceptional precision positioning across all major GNSS constellations and frequency bands:

• GPS/QZSS: L1, L2, L5, L6
• GLONASS: G1, G2, G3
• Galileo: E1, E5a, E5b, E6
• BeiDou: B1, B2, B2a, B3
• NavIC: L5
• SBAS: WAAS (North America), EGNOS (Europe), MSAS (Japan), GAGAN (India)
• L-Band Correction Services

Advanced Helical Design

The HC3990XF features Calian’s latest wideband helical element, delivering optimal performance without a ground plane.

• Upper GNSS Band & L-Band: 67 MHz bandwidth (1539–1606 MHz)
• Lower GNSS Band: 136 MHz bandwidth (1164–1300 MHz)

Its superior axial ratio ensures accurate capture of RHCP signals while rejecting LHCP reflections, resulting in excellent multipath mitigation and a highly stable phase center.

Lightweight & Versatile

Weighing just 105 g, this compact antenna is ideal for applications where size and weight matter—such as unmanned aerial vehicles (UAVs). The precision-tuned helix element provides outstanding axial ratios and operates without a ground plane.

eXtended Filtering (XF) Technology

With global RF spectrum congestion and emerging LTE bands, interference is a growing challenge. Calian’s XF technology effectively mitigates disruptive signals, including:

• Ligado (North America): 1526–1536 MHz
• LTE Band 32 (Europe): 1452–1496 MHz
• LTE Bands 11 & 21 (Japan): 1476–1511 MHz

Durable & Installation-Ready

The HC3990XF comes in a weatherproof, through-hole mount enclosure for permanent installations. Optional accessories include:

• L-Bracket (PN 23-0040-0)
• Pipe Mount (PN 23-0065-0)
