proTAC8004™ all-band anti-jamming and anti-spoofing GNSS antenna

One of the key advantages of our anti-jamming and anti-spoofing proTAC8004™ all-band GNSS antenna is its unique mechanical and RF design that attenuates low-angle interference, reflected signals, and multipath effects. Instead of accepting all incoming signals equally, the antenna is optimized to prioritize direct satellite signals while suppressing reflected and near-horizon signals that typically cause instability, positioning oscillation, and degraded accuracy.

Key benefits of proTAC8004™:
• True all-band GNSS support
Supports GPS, Galileo, GLONASS, BeiDou, QZSS and NavIC across L1/L2/L5/L6 and corresponding bands.
• Excellent anti-jamming and anti-spoofing performance
• Mechanical and RF filtering against low-angle interference
The antenna structure helps attenuate low-angle jamming and reflected multipath signals while prioritizing direct satellite signals.
• Improved stability and accuracy
By suppressing reflected signals, the system minimizes positioning oscillation (“position wobble”) and improves signal stability.
• Future-proof architecture
Designed for modern multi-frequency GNSS environments and evolving resilient PNT requirements.

While proTAC8004 is not a CRPA antenna with active beam steering and nulling capabilities, it still provides significant practical interference mitigation benefits through its antenna pattern design, filtering characteristics, wideband architecture, and multipath suppression performance. In many applications, this offers an excellent balance between resilience, complexity, size, integration effort, and cost.
