The growing drone threat
Three incidents explain why counter-UAS budgets moved from pilot projects to capital lines. None of them required military hardware: a consumer airframe, a payload measured in kilograms, and a target that was not designed to look up.
19-21 Dec 2018
Gatwick Airport, United Kingdom
Reported drone sightings at the perimeter closed the runway for roughly 33 hours. Around 1,000 flights were disrupted and about 140,000 passengers were affected. No operator was ever confirmed, which is the part procurement teams should notice: the response has to work on a sighting, not on a conviction.
14 Sep 2019
Abqaiq and Khurais, Saudi Arabia
Low-altitude unmanned aircraft struck oil processing facilities and temporarily removed a large share of the country national crude output. The attack showed that a small airframe with a modest payload can produce strategic-level disruption when the target was never designed to look up.

Prison perimeters and event venues
Contraband deliveries over prison walls and unauthorised flights over crowded venues are weekly events rather than headline incidents. They rarely make the news, but they are the deployments most buyers actually fund first, because the cost of one successful drop or one cancelled event is immediate.
The economics are what drive procurement. A quadcopter with a camera costs a few hundred dollars; closing a runway for a day costs an airport operator many thousands per minute in lost slots, compensation and crew rescheduling. The defender pays for coverage of a perimeter that may be tens of kilometres long, while the attacker needs one gap.
That asymmetry is why detection range, not jammer power, is usually the deciding specification. If you find the airframe at 200 metres you have seconds; at 5 kilometres you have a decision process.
Our anti-drone product line
Four delivery formats share the same amplifier and antenna building blocks, which is why a handheld unit and a fixed tower can be serviced from one spares kit. Ranges assume line of sight; urban sites shorten them.

| Backpack multi-band system | 50 W per band set | 500-1500 m | Dismounted patrol use, 360-degree or directional antenna options | backpack drone jammers |
| Portable case system | 50 W per band | 500-3000 m | 8 bands from 400-5860 MHz, built-in antennas, transport case | high-power portable systems |

GaN technology advantage
Gallium nitride is not a marketing word in this product category; it changes what fits in a backpack and what survives a field failure. These are the six consequences we design around, including where GaN is the wrong choice.
More output per stage
A GaN device delivers roughly three to five times the power density of the silicon LDMOS parts it replaced in our designs. That means fewer amplifier stages between the exciter and the antenna, which shortens the signal chain and removes the inter-stage losses and connectors that fail first in humid or dusty cabinets.
Tolerance for a damaged antenna
Field units lose antennas: a bent connector, a cut feeder, a mast that took a hit. GaN transistors have a higher breakdown voltage, so the output stage survives the reflected power long enough for the VSWR protection to fold the drive back. With older bipolar stages this is where units died and came back for repair.
Bandwidth per board
One GaN stage can cover an octave or more, so a 900 MHz and a 1.5 GHz channel can share a smaller enclosure, or a 2.4 GHz and 5.8 GHz pair can sit on one heatsink. For a backpack unit that matters: less weight, fewer battery cells, and a shorter warm-up before the operator can transmit.
Known efficiency at high ambient
At full output the stages run at roughly 55 percent drain efficiency, and the number is measured at the ambient temperature of the target market rather than at 25 degrees Celsius. A unit rated for 50 W at 45 degrees is not the same product as one rated for 50 W on a bench in an air-conditioned room.
Simultaneous bands without fighting
Multi-band jamming only works if the channels do not interfere with each other inside the box. Filtering, isolation and layout between adjacent bands decide whether a 2.4 GHz and 5.8 GHz channel can transmit at the same time, or whether the operator has to switch. This is an amplifier and filter design problem, not a marketing feature.
Where we still use LDMOS
Below about 500 MHz at moderate power, LDMOS remains cost-effective and robust, and we say so in the quotation instead of quoting GaN everywhere. The choice is made per band and per target price, and the datasheet you receive states which technology is inside each channel.
Deployment scenarios
Five site types account for most of our anti-drone shipments. Each one fails differently, so the specification that matters changes with the site.
Airports
An airport needs graded response, not a single switch. The workable architecture puts RF detection and direction finding along the approach corridors, a decision layer in the security room, and jamming as the last step rather than the first. Detection to 20 km gives the operator time to identify the airframe and its track; suppression at 5 km covers the critical zone without reaching into the approach path. Every engagement is logged with band, time and bearing so post-incident review and regulatory reporting use the same record.
Prisons
Contraband drops over a perimeter wall are short, low, and often at night, which is why fixed coverage beats patrols. Directional panels aimed outward along the wall, with output kept low enough that neighbouring streets and the prison own radio system stay unaffected, handle most incidents. The system runs unattended with remote monitoring, and the log tells staff which sector triggered, so a search can start at the right place instead of the whole compound.
Critical infrastructure
Refineries, substations, water plants and pipelines share a problem: the site is large, remote and cannot host a permanent operator. Equipment here is specified for unattended duty, usually 24 V or 48 V DC from the site battery bank, in an IP65 enclosure that survives dust and rain, with surge protection on every input. Detection runs continuously; jamming is armed by the control room on confirmation, so a bird or a plastic bag does not trigger a transmission.
Event security
A stadium or a summit needs coverage for days, not years. Portable case systems and backpack units are deployed after a spectrum survey of the venue, because the frequency plan has to be agreed with broadcasters, organisers and local regulators before anything transmits. Operators are briefed on the difference between a media drone with clearance and an unauthorised airframe. The equipment is chosen for fast setup, clear status indication and a record of what was transmitted and when.
Borders
A border sector is a long perimeter with intermittent infrastructure, so the architecture combines fixed towers at crossing points with vehicle-mounted units for response. Detection nodes report bearing and band; the response vehicle closes the distance and engages. Power comes from the vehicle or a solar-battery site, which sets the practical limit on output per channel. Wide temperature range and dust sealing matter more here than peak power on a datasheet.
Frequency bands and power comparison
Power figures are continuous output per band at the stated ambient, not peak. More output is not automatically better: the useful question is whether the emission at the perimeter stays inside what the local regulator allows.
| Band | What it carries | Module power | Effect on the airframe | Design note |
|---|---|---|---|---|
| 433 MHz | RC links on low-cost airframes, telemetry | 10-30 W | Loss of manual control on older platforms | Rarely used by DJI-class aircraft but still present in improvised builds |
| 900 MHz | Long-range control links, some telemetry | 20-50 W | Control loss beyond visual range | Regional ISM differences; band checked against local allocation |
| 1.2 GHz | Analogue and some digital video downlinks | 20-50 W | Video feed degrades before control is affected | Useful on FPV airframes, less relevant to consumer models |
| 1.5 / 1.575 GHz (GNSS L1) | GPS and GLONASS positioning | 10-50 W | Position hold fails, return-to-home becomes unreliable | Narrowband filtering keeps the emission inside the GNSS allocation |
| 1.2 / 1.6 GHz (GNSS L2) | Dual-frequency GNSS receivers | 10-30 W | Closes the fallback path on dual-band receivers | Optional channel; adds cost and heat to the enclosure |
| 2.4 GHz | Primary control and video link on most consumer drones | 30-100 W | The single most effective band on DJI-class airframes | Also carries WiFi, so site WiFi planning matters |
| 5.2 GHz | Video downlink, some control channels | 20-50 W | Video loss and reduced range | Band edges vary by region; channels are set at order |
| 5.8 GHz | Video and control on higher-end airframes | 30-100 W | Video loss, forced descent or return-to-home | Pairs with 2.4 GHz for simultaneous dual-band engagement |
Frequently asked questions
What is the difference between drone detection and drone jamming?+
Detection listens: RF receivers and direction-finding antennas identify that an airframe is transmitting, on which band, and from which bearing. Jamming transmits on the same bands to break the control and video link. A detection-only site tells you something is there; a jamming-only site transmits blind. Most funded projects combine both, with detection driving the decision to engage.
How far can your systems detect and suppress?+
The integrated detection-and-strike platform reaches 3 to 20 km on detection and 5 km on suppression, depending on antenna height and terrain. Portable systems are shorter: 500 to 3000 m for the case units, 500 to 1500 m for backpack sets, and 1 to 1.5 km for handheld guns. All ranges assume line of sight to the airframe, which is the assumption that fails first in urban sites.
Which bands must be covered to stop a consumer drone?+
For most DJI-class aircraft, 2.4 GHz and 5.8 GHz cover the control and video link, and GNSS L1 removes position hold and reliable return-to-home. That three-band set handles the majority of consumer incidents. Adding 900 MHz and 433 MHz widens coverage to older and improvised platforms, and 1.2 GHz helps against FPV airframes, at the cost of size, heat and price.
Do you offer GPS spoofing as well as RF jamming?+
GNSS spoofing channels are quoted on request, only for authorised projects and only where the buyer holds the required national approval. Spoofing carries legal and safety exposure that jamming does not, since a misled receiver can be directed rather than simply disabled. In most projects a jamming-only configuration is easier to approve and to defend in an incident review.
Can the system integrate with our existing CCTV or command platform?+
Yes. Detection modules output bearing, band and timestamp over a documented interface, and the control unit accepts dry-contact and serial triggers from third-party systems. Integration depth depends on what the site already runs; we ask for the existing architecture before quoting, because retrofitting a protocol later costs more than choosing the right interface at order stage.
What documentation is required to purchase anti-drone equipment?+
Authorised end users only: government agencies, military and police units, correctional and airport authorities, critical-infrastructure operators and licensed integrators. Orders require a stated end use and, where the destination requires it, an import authorisation. We supply serial-numbered test reports, declarations and export documents with each shipment, and we decline orders where the end use cannot be established.
How is a fixed outdoor site powered and protected?+
Fixed installations run from 24 V or 48 V DC, usually from a site battery bank with mains or solar charging, in IP65-rated enclosures with surge protection on power and antenna feeds. Continuous detection draws little; jamming is the load that sizes the supply. We ask for the ambient temperature range and the dust environment before specifying heatsink and coating, because those two numbers decide field life.
What happens after delivery if a unit underperforms?+
Start with the measured data: forward and reflected power, flange temperature, supply voltage and the band that failed. Most underperformance traces to a damaged feeder, a wet connector or an undersized supply, all diagnosable remotely from those four readings. If a module is at fault, spare amplifiers and cables ship with the original order so a site can be restored without waiting for an RMA cycle.
