Why MOTH
The spectrum is always active. MOTH makes RF activity visible and actionable in a body-worn analyzer built for the field — from first alert to waveform investigation and logged evidence.
- Frequency coverage: 5 MHz–6 GHz
- Scan rate: 5 / sec
- Battery life · 24 Wh: 12 hr
- Ingress protection: IP67
From first alert to signal analysis.
A field workflow
Detect
A wide view of the RF environment.
MOTH covers 5 MHz to 6 GHz and scans five times per second. Wear it while moving through the environment; vibration alerts call attention to detected activity.
Investigate
Move from alert to waveform.
Use Spectrum View to investigate signal waveforms in real time. Night mode supports low-light use, and the screen measures 2.79 inches at 240 × 320 pixels.
Direction finding helps guide the operator toward a signal source. MOTH logs detections for download and connects with ATAK, Lattice, and MAVLink via USB-C. An SDK is available for custom integrations.
Built for the field
Rugged where it counts.
MOTH combines IP67 ingress protection with an operating range of 14–131°F (-10–55°C). At 0.99 lb with battery and antennas, it is built to wear in the field.
The 24 Wh battery delivers up to 12 hours of operation.

What can I do after MOTH detects activity?
Vibration alerts notify you of RF activity. Use direction finding to locate its source, inspect waveforms in real time with Spectrum View, and log detections for download and later analysis. Night mode supports low-light operation.
