A stationary drone jammer offers greater power, longer detection range, and lower operating costs when protecting a fixed asset than a mobile unit. A mobile solution is the only way to defend an asset that moves – or an operating space whose risk profile shifts location over time. Eventually, all effective anti-drone defences need both systems operating in a complementary fashion as part of a cohesive airspace defence.
The wrong decision will not simply throw money away; it will create the most valuable vulnerability an adversary can exploit. Use this guide to choose the correct plan.
What Fixed Drone Jammers Do Well
The “fixed installation” jammers are by far the most potent range within the family of drone jammers. Bolted in place at an agreed site – this could be on a rooftop, a tower, a perimeter mast, or a specially constructed site – they have only one goal: to define and maintain a “protected airspace bubble” around a static asset on a 24/7 basis. No supervision or intervention by a human operator is ever needed.
Stationary jammers have the strongest power output and are permanently integrated in government buildings, airport sites, etc. And the durable structure will effectively cover a larger area and ensure reliable performance. These stationary jammers protect the locations from drones with wider area protection, multiple frequencies’ jamming capability and excellent reliability.
Since the static systems use power directly from the building or infrastructure power grid, there are no battery limitations or vehicle power constraints, meaning that static systems can provide a higher constant output power than any mobile system, allowing for a longer actual jamming range, more simultaneous frequency bands, and security in place around the clock, 365 days a year, with no crew on site.
They are better integrated into the existing security architecture than fixed systems. This means that they will interface with the video surveillance systems, access control systems, alarm systems and the operational centre for the site security. When the system detects the drones, the action taken may also be automated (alert, log, jam, or notify) without human intervention every time. Automation is a big saving on sites that are subjected to continuous risk from drones.
The compromise is a complete lack of flexibility. A static jammer only protects the spot where it is installed. As soon as a protected convoy, vehicle, or individual leaves that spot, he is out of the safe area.
What Vehicle-Mounted Drone Jammers Do Well
Mobile units have a greater range and greater output of protection, which allows for the security of a much larger range, such as perimeter security or on-board mobile patrols. The most important aspect of the mobile units is that protection comes with your asset. The jamming bubble moves with you – it is present anywhere that the vehicle moves, not just at points A and B.
Fixed sites, in contrast, are tactically useless for applications like protecting the VIP convoy, securing the border or operating in a military theatre. You simply cannot have a 200 km-long stretch of fixed jammer assets to protect a military convoy; you can’t have it for a border patrol vehicle that patrols 10 km of perimeter, and you cannot guarantee that fixed assets have been positioned on every route that a VIP may be using.
What vehicles offer as well is operational flexibility that fixed sites do not; they can be moved from the site to the event or deployed anywhere as needed. If the site of a threat, exercise, or operation shifts, the vehicle will shift with it. There is a real monetary benefit as well, as the protection has effectively been “reassigned” from one site to another versus a fixed system that can only ever protect one site in perpetuity.
Constraint power and permanence. A mobile system mounted in a vehicle draws its energy from the electrical system of the vehicle, limiting output power at the high end compared to the electrical system of a fixed installation supplied with electricity. The jamming range on vehicles extends on average to 3 km, with an extension up to 5 km. Some high-end fixed systems can largely extend this range for the more capable. Systems installed on a vehicle need a crew to be driven and to man this anti-drone system ideally.

Six Questions to Determine Your Deployment Model
1. Does Your Protected Asset Move?
This first and foremost question determines it all. Is the answer ever “yes”? If so, it is a mounted unit, not a power station whose security officer must relocate. A ministry does not relocate; the minister does. These seemingly stationary operations invariably include mobility that carries the same security risks.
2. What Is the Threat Dwell Time at Your Location?
If you have persistent and continued exposure to the threat in a familiar fixed location, then a fixed system will offer optimum long-term benefits. You have drone intrusions on a day-by-day or day-per-week basis, and a fixed installation of automated systems makes the best strategic sense. If you have isolated and irregular threat events, the cost-benefit will favour a mobile solution that can track with the event.
3. How Large Is the Area You Need to Protect?
Fixed systems are best used for defending a finite and contained perimeter. A single well-designed fixed-site system, with accurately sited sensors and jamming modules, could provide complete aerial coverage over an airport, a power station or even a prison. Vehicular systems have a radius of coverage centred around the vehicle, roughly 3 kilometres in radius, but this radius is moving with the system, making it useful for patrolling and securing a linear or extensive boundary.
4. What Is Your Budget Model — CapEx or OpEx?
Fixed installations have a greater upfront capital outlay: survey, civil works, power supply, integration, and commissioning before the system is in place and functional. Post-commissioning operation is very low cost, mostly run with limited human input and with required maintenance periods. Vehicle-mounted systems have reduced upfront equipment costs but incur higher operating costs: crew, vehicle operating costs and human overhead to operate and maintain a manned CUD patrol. For a five-year lifecycle, costs would vary in comparison, depending on operational activity and requirements.

5. What Is Your Required Response Time?
A fixed system with autonomous detection and jamming takes action against a drone threat within seconds, with no user intervention. The delay with a vehicle-based system is the presence of crew. For a zero-tolerance installation against a detected drone during the hours when drones typically do not have free rein, a fixed system with an autonomous response is the only suitable architecture. Vehicle-based systems are ideal for situations where the presence of crew during potentially risk-filled periods is feasible.
6. How Predictable Is Your Threat Geometry?
Fixed systems are ideally suited for situations in which the approach geometry is well understood and static – drones attacking into a perimeter from beyond, following consistent vectors towards an area at the centre that needs protecting. Vehicle-mounted systems account for arbitrary geometry by providing a coverage bubble that moves and shapes itself to the vehicle’s current situation. When operating across open terrain or a fluctuating road route, and in scenarios when threats could attack from any direction at any time, mobile coverage inherently accounts for geometry.
When You Need Both: The Hybrid Approach
The best-performing drone defence system architectures integrate both vehicle-mounted and static-based elements as two distinct and integrated complementary layers, and not as a substitute.
A typical hybrid setup includes an in-base or in-facility system. This system provides wide, strong coverage at home. It also fully integrates with the current security infrastructure. Vehicles are deployed with the coverage of mobile threats along convoy roads, for advanced use and movement by mobile personnel who move off-site. The mobile system and stationary system integrate information from the system and present a unified, complete situation awareness at the command-control system, enabling the operator to control both mobile and stationary situations simultaneously.
This stratified perspective indicates the destination the EU Counter-UAS Action Plan is pushing European critical infrastructure operators toward – coordinated multi-layer airspace security that covers both fixed and mobile threats without addressing each component in an individual manner.

Frequently Asked Questions
Can a vehicle-mounted jammer replace a fixed installation at a critical infrastructure site?
Fixed installations are more powerful and integrate more efficiently for better security. They operate 24/7 independently. Vehicle-mounted installations cover the asset or person once the user leaves the protected area and complement rather than replace your fixed installation.
Is a fixed jammer always more powerful than a vehicle-mounted system?
They utilise mains power and thus are capable of higher power across several frequency bands and further ranges. This, of course, does nothing for someone needing jammer coverage of their vehicle 300 km away from the nearest available installation that utilises 10 km fixed jammers.
How quickly can a vehicle-mounted jammer be deployed compared to a fixed system?
How soon will vehicle systems work after installation? Will it be ready to move the same day? It can take days to weeks to install a fixed-type system in vehicles. If you need it fast, this is the quickest option.
Do both system types require government authorisation to operate in Europe?
In the EU, drone jammers come under national telecommunications law. Use by the general public is forbidden unless authorised. This legislation strictly prohibits civilians, as well as private companies or any individuals (unless explicitly acting under the authorisation of the authorities, the armed forces, or law enforcement officers), from deploying these types of jammers.
What happens to fixed jammer coverage when I need to relocate my operation?
Vehicle-mounted and portable systems: Vehicles If you are relocating or just changing site locations regularly, a fixed monitoring system is completely useless. Vehicle-mounted or portable fire alarms would, of course, travel with you. Organisations often utilise a combination of systems, with fixed systems covering the main base while using mobile systems for the travelling workforce.
