Passive drone detector and direction finder
Passive handheld drone detector and direction finder. 100 MHz – 13 GHz. Detection range up to 5 km. 200 g.
The problem
Most drone detectors recognise a drone only if its signature is already in their library. When a drone gets new or modified equipment, those detectors stop seeing it until the next firmware update arrives. Switch the library off, and they react to every phone, radio, cell tower and router around you.
How it works
BLIP 13 does not need to know what a drone is. It sees that something is moving toward you.
Two modes, one device
Omnidirectional whip: 360° early warning, nothing to aim. Arrow: the direction to the drone, up to 5 km away. Both antennas come in the box — fit the one the task needs.
With the omnidirectional whip, BLIP 13 watches every direction at once — no turning, no aiming. Set it on a tripod, a table or the ground at a post, and it raises the alarm the moment a drone transmits within range.
The log-periodic Arrow antenna on the pistol grip turns BLIP 13 into a direction finder. Sweep the horizon: the bearing is where the signal is strongest. A narrow beam reaches farther and leaves out the noise behind you.
Smart interference handling
Cities, bases and convoys are full of radio. BLIP 13 learns what is already on air and alerts only on what is new.
Auto-Exclude
Press Auto-Exclude and BLIP 13 adds everything currently on air — cell towers, Wi-Fi, radios — to its exclusions. From then on it reacts only to new signals. Each further press adds the newest sources to the list. Excluded signals stay visible on the graph in green.
The band itself is never switched off. If a drone comes up next to an excluded cell tower, on the very same band, BLIP 13 still raises the alarm.
Manual Exclusions
Set up to 12 frequency bands the device should ignore, each with its own start and end frequency — your team's radios, your own data links, a known transmitter on site. They show on the graph in light blue and stay saved after a restart.
Signal Hold
Many drones keep jumping from frequency to frequency. Signal Hold keeps every signal on screen after it disappears, so a hopping drone stays visible between jumps instead of flickering in and out. You set how many sweeps a signal is held and how fast it fades.
Why BLIP 13
Wider coverage, no signature library, live spectrum in your hand and direction finding in the standard kit.
Wearable detectors from leading Western makers stop at 6–7 GHz. BLIP 13 covers the full X-band.
Published receiver ranges, October 2026. Product names are trademarks of their respective owners.
Drone Only mode ignores static emitters and alerts on approaching targets. No signature library, no subscription, no database updates.
Only BLIP 13 has this capability. As of October 2026, BLIP 13 has no equivalent.

Integration
BLIP 13 is a handheld detector and a sensor for a fixed post. One USB-C cable to a PC, four programmable outputs to everything else.
USB-C → PC
4 × TTL outputs → anything
3 V pulse on every new detection, programmed on the device itself — no programmer needed.
EW Monitor
BLIP 13 remembers the signal levels of your own EW system in every band. If they drop — the jammer fails, overheats or is switched off — it sounds an alarm and shows a warning. Your team knows the cover is down before a drone does.
In the field
Passive in detection mode: BLIP 13 emits nothing and gives nothing away. It alarms on what is approaching, not on the noise around you.
Where it works
Energy sites, ports, stadiums, close protection, checkpoints, winter field work.
01 · Personal
Personal early warning that weighs 200 g. Fully passive in detection mode — nothing to give away your position. Silent text alerts when sound is not an option.
02 · Site
Critical infrastructure, industrial sites, events and private property. With the omnidirectional antenna, BLIP 13 watches 360° without being turned.
03 · Fixed post
Connect BLIP 13 to a PC over USB-C for a large-screen spectrum view and remote access over the Internet or LAN. Four programmable TTL outputs trigger alarms, perimeter automation or EW systems on every new detection.
Kit and price
In the box
Option
Any drone that transmits radio signals — FPV, commercial and specialized, fixed-wing or multirotor — through its control, video and telemetry links. It also detects relays, beacons and handheld radios.
No. In Drone Only mode BLIP 13 detects targets by their movement, not by signatures, so new and modified drones are detected without updates.
Up to 5 km with the Arrow directional antenna and up to 2 km with the omnidirectional whip. Range depends on the drone's transmitter power, terrain and line of sight.
No. In detection mode it is a passive receiver and emits nothing.
Up to 8 hours of continuous operation. It charges over USB-C from a phone charger and runs from a power bank.
