TinySA Ultra is a portable RF spectrum analyser and UAV detector designed for monitoring and analysing the radio-frequency environment in field conditions.
The device detects and alerts the operator to RF activity from UAVs and other transmitting devices across the 100 kHz–6 GHz frequency range. This includes signals associated with a wide range of platforms and services, including Lancet, Orlan, Zala, FPV and DJI systems, as well as Wi-Fi, radio and mobile communications, GNSS-related signals and the operation of electronic warfare systems.
TinySA Ultra operates in receive-only mode and does not transmit RF signals. Spectrum activity is displayed directly on the touchscreen, allowing the operator to view signal frequency, power and activity in real time. The device is supplied with dedicated military firmware and a built-in signal amplifier.
Key Advantages
One device for a wide range of RF monitoring tasks. The 100 kHz–6 GHz operating range covers a broad spectrum of signals without requiring separate detectors for different frequency bands. With the supplied directional log-periodic antenna, the system detects RF sources across 800 MHz–6 GHz at distances of at least 5 km within a 60° sector under suitable conditions.
Real-time spectrum visibility. The touchscreen displays signal frequency, power and activity in real time. Instead of receiving only an alert, the operator can assess the characteristics and relative strength of detected RF activity.
Passive operation. TinySA Ultra operates only as a receiver and does not emit RF signals, reducing its electromagnetic signature and making it suitable for use at forward positions, observation posts and during reconnaissance tasks.
Detection of hidden transmitters. The device can also be used to locate covert transmitters and unidentified RF sources during inspections of buildings, vehicles, equipment and deployed positions.
EW system monitoring. TinySA Ultra can be used to identify active frequency bands and perform basic checks of electronic warfare system operation. When working near active EW equipment, a minimum distance of 15 m is recommended, depending on transmitter power and antenna type.
Designed for field use. The device features a dust- and splash-resistant enclosure and is supplied with a tripod and shoulder strap. It can also be powered or charged from a power bank.
Applications
- Detection of RF emissions from FPV drones and other UAVs
- RF spectrum monitoring at deployed positions and observation posts
- Analysis of active frequencies and electronic warfare system operation
- Detection of hidden transmitters and unidentified RF sources

Important: Protecting the Device When Operating Near EW Systems
TinySA Ultra is a receiving device with a sensitive RF input stage. The maximum permissible input level is +6 dBm, or approximately +10 to +15 dBm when using the built-in attenuator. Signals exceeding these levels may damage the receiver input stage.
When locating or analysing electronic warfare systems, the device may be used close to high-power RF emitters such as EW stations, GNSS jammers, UAV control-link jammers and transmitters operating at power levels ranging from several watts to tens of watts.
At distances of only a few metres from a powerful transmitter, the RF level reaching the antenna may exceed the safe input level and permanently damage the receiver.
Recommended Solution: External 50 Ω SMA Attenuator
- Attenuation: 20–40 dB, selected according to the expected source power
- Frequency range: up to 6 GHz or higher
- Power rating: at least 2 W; 5 W or higher is preferable when operating near EW transmitters
- Connectors: SMA male / SMA female, installed between the antenna and the device
An external attenuator also allows the operator to measure stronger signals more accurately. Without sufficient attenuation, high signal levels can overload the receiver and distort the displayed spectrum.
Why Use an External Attenuator?
The built-in attenuator provides only limited protection when the device is operated close to powerful RF sources. An external attenuator reduces the signal level before it reaches the receiver input, absorbing much of the excess RF power before it can affect the sensitive input stage.
Regular operation near active EW systems without adequate protection may reduce the service life of TinySA Ultra. For devices frequently used in the field near high-power RF emitters, an external attenuator is a simple and cost-effective way to protect the receiver.
