25 July 2024

A drone jammer—also called a drone jammer gun—is a device designed to bring a drone to the ground.

It works by disrupting the radio signal that controls a drone, allowing you to ground them by blocking their communication system.

The drone industry is currently experiencing exponential growth with no signs of slowing down.

But with all these drones in the air, there’s now a big challenge—how do you keep drones out of restricted airspace?

The FAA has worked hard to ensure both drone pilots and the general public adapt to the evolutionary phase we’re currently experiencing.

But despite its best efforts, the introduction of drones into commercial airspace hasn’t been entirely smooth, and rogue drone incidents seem to be happening more and more frequently over sports events, at airports, and elsewhere.

In this article, we are going to cover what drone jammers are, the top drone jammers on the market, the legality of using them, and whether or not you need to be worried about encountering one as a drone pilot.

Here’s a menu in case you’d like to jump around:

What Is a Drone Jammer?

A drone jammer gun is a gun-looking device made to bring a drone to the ground.

How Does a Drone Jammer Gun Work?

A drone jammer works by sending electromagnetic noise at radio frequencies with the purpose of overriding the same radio and GPS signals your drone uses to operate.

A drone jammer gun’s frequency is generally assigned at 2.4Ghz or 5.8Ghz which are public frequencies non-assigned to manned aircraft, public broadcasts or cell phone signals.

Drone jammer guns will often look similar to guns (see above) and operate by projecting the jammer signal in the shape of a cone of about 15-30 degrees.

When a drone gets hit with the jammer’s signal, the most common response is for the drone to return back to its point of origin (unless GPS is also jammed), giving the jammer operator the option to track the drone back to the pilot. In some cases, a drone jammer may cause the drone to land on the spot in order to conduct a forensic investigation.

The most heavy-duty drone jammers on the market can work from up to almost a mile away and are increasingly more effective as the pilot’s remote gets further from the drone.

Alternative CUAS

Drone jammer guns are actually a win-win for both drone pilots and controlling agencies, since they typically preserve the drone and present fewer risks than other drone countermeasures.

Drone jamming by radio signal is the preferred and safest method for controlling rogue UAVs.

Here are some other ways to deal with a rogue drone:

  • Drone netting. If a drone breaches a jamming signal, depending on the situation, larger drones carrying nets can be deployed to physically snare a rogue UAV and bring it out of the sky. In this scenario, a drone falling from the sky is more likely, and the pilot will probably not get the drone back in one piece, if at all.
  • Shoot the drone down. During the South Korean Olympic games in 2018 the security staff had cUAS protocols of actually shooting rogue drones out of the sky should the situation escalate. Fortunately, this did not need to happen, and instead, people will forever remember the amazing synchronized drone performance put on by Intel.
  • Trained bald eagles. We kid you not. Dutch authorities have trained eagles to take drones out of the sky.

Bottom Line: Civilians and Local Authorities Are Not Allowed to Use Drone Jammers

Domestically, the United States federal government does not allow state or local authorities to pursue action against drone pilots, even when a drone is being flown illegally.

While it may seem strange that our local authorities do not yet have the means to take action, analysts of the technology believe it will be a good thing to develop standards on a Federal level so parties inherently biased against drone use cannot take matters into their own hands.

In scenarios where drones pose a security threat, such as near airports or in conflict zones, federal authorities may deploy jamming technology. However, the complexity of safely integrating these systems in environments dense with electronic communication makes their use challenging:

  • Airport safety concerns. Airports are hubs of intensive radio communication where the introduction of a drone jamming device could disrupt essential communications, potentially affecting commercial aviation safety.
  • Operational challenges. Effectively operating a drone jamming system requires precise identification and targeting of UAVs, which demands significant manpower and technological resources, often making it impractical for local enforcement.
  • Economic considerations. The high costs associated with installing comprehensive drone detection and neutralization systems pose another barrier, particularly when weighed against evolving drone technology.
  • Legal and enforcement limitations. Even at the federal level, enforcement actions against unauthorized drone operations are rare. From 2007 to 2018, there were fewer than 50 legal actions related to drone misuse, highlighting the difficulties in policing drone operations effectively.

Given these factors, local authorities often find themselves unable to act against illegal drone activities, leading to calls for clearer federal guidelines and more accessible counter-drone technologies.

The ongoing development of these standards aims to ensure that local biases do not compromise the fair enforcement of drone regulations.


Where Drone Jammers Are Being Used

Since drone jamming is limited legally to the federal government, the current applications of the technology are being reserved for high profile events and within operations directly related to the secret service and military.

One of the first public statements made in regards to signal jamming and government safety occurred back in 2015 after a drone crash landed on the white house lawn.

More recently, before the attempted assassination of former President Trump on July 13, 2024 the shooter used a drone to surveil the site. This is exactly the type of scenario where a drone jammer could have been useful.

Use Cases for Drone Jammers

Drone jammers are primarily utilized by the federal government due to strict legal restrictions on their use.

These devices are deployed in scenarios where security is paramount, such as national security operations and protection of significant public figures or events.

Here’s a closer look at the typical applications of drone jammers:

  • Government Security. Following incidents like the 2015 drone crash on the White House lawn, federal agencies have significantly increased the use of drone jammers to secure critical infrastructures and residences of high-profile government officials, including the White House.
  • Military Operations. In military contexts, drone jammers are crucial for protecting personnel and sensitive locations from espionage or attacks by hostile drones. They are used both in domestic bases and during overseas operations to create drone-free zones.
  • High-Profile Events. Events that attract large crowds and extensive media coverage, such as the Olympics or the Super Bowl, often employ drone jammers to prevent unauthorized drone activities that could disrupt the event or compromise safety. For instance, during the Super Bowl at the Mercedes-Benz Stadium in Atlanta, drone jammers were part of a comprehensive security strategy that included both performance choreography and surveillance.
  • Counter-terrorism. Drone jammers are a key component in counter-terrorism strategies, especially in urban areas or during significant public gatherings, to thwart potential threats from drones used in terrorist activities.

What Drone Pilots Should Know about Drone Jammers

Drone jammers, although a critical tool for federal security and authorized entities, present a significant consideration for civilian drone pilots. Here are essential insights every drone pilot should be aware of regarding drone jammers:
