50–400 MHz. Up to 12 m Depth. Maximum Versatility.
The Zond Aero LF's unshielded dipole antenna architecture supports the full 50–400 MHz frequency range — the widest of any system in the Radar Systems portfolio. Three antenna sets (100, 150, and 300 MHz) are included as standard; custom frequencies are available on request, and supplied dipoles can be field-trimmed to achieve a specific center frequency without additional hardware. Real-Time Sampling (RTS) with high hardware stacking delivers scan rates up to 2,500 scans/s and sample rates up to 1,280,000 — capturing 32-bit raw data with selectable time ranges from 18 ps to 2.5 ns for precise subsurface profiling at depths up to 12 m. Data is output in SEG-Y format with trace geotagging for direct GIS integration.

The Radar Systems Zond Aero LF is an ultra-lightweight, multi-frequency low-frequency UAV GPR system engineered for deep subsurface penetration and maximum survey versatility. Featuring Real-Time Sampling (RTS) technology with high hardware stacking, it delivers high-resolution, low-noise data across a selectable frequency range of 50–400 MHz — making it the most frequency-flexible GPR system in the Radar Systems portfolio.
The system ships with three antenna sets (100, 150, and 300 MHz) and supports custom frequencies across the full 50–400 MHz range by request. Dipoles can even be field-trimmed to achieve a specific center frequency — giving operators unmatched adaptability across survey conditions and target depths.
Deployment
- Airborne (UAV) — Drone-mounted for large open-area deep-penetration surveys; powered directly from the drone's main battery; compatible with medium-sized UAVs (drone mountings included)
