The jammer antenna is also a very important part of the jamming equipment! We have previously analyzed: "What is the difference between an internal antenna signal jammer and an external antenna signal jammer?" Now let's talk about the types of jamming antennas and how to choose the most suitable jamming antenna for you.
Do you know how important the jammer antenna is? Choosing a suitable jammer antenna is crucial as it directly affects the jammer's performance, jamming range and application scenarios. I will explore the different types of jamming antennas and provide important criteria for selecting the best jammer antenna to help you find the right solution for your specific needs.
Main types of jammer antennas
There are many types of jamming antennas, each with a different operating principle and application scenario. Let's analyze some common jammer antenna types:
1. omnidirectional interference antenna
Features:
- 360° all-round signal coverage
- Suitable for environments where a broad interference spectrum is required
- Mainly used for car jammers and stationary jammers
Applicable scenarios:
- Vehicle-mounted jammer
- Signal interference in conference rooms and examination rooms
- Prevent GPS tracking
Selection proposal:
If you want to emit interference signals evenly in all directions to disrupt wireless communication signals in the surrounding area, an omnidirectional interference antenna is the best choice. For example, vehicle-mounted GPS jammer Often omnidirectional antennas to ensure that all GPS devices around the vehicle cannot receive signals properly. The articles I have previously written about GPS signals are: "Are GPS jammers effective against trackers?" and "To block the GPS tracking of your vehicle".
2. directional interference antenna
Features:
- The signal is concentrated in a specific direction
- Longer interference distance and stronger performance
- Suitable for targeted jammer applications
Applicable scenarios:
- Areas that require precise intervention in a specific direction
- Research Institute for Radio Signal Research
Selection proposal:
Did you know that directional jamming antennas are more expensive than omnidirectional jamming antennas? For most cell phone or GPS signal interference in our work and private lives, a directional jammer antenna is not necessarily required. I still recommend that you buy an omnidirectional jammer antenna. If you want to jam signals in a small area, you can buy a jammer with low output power. If you need to jam a large conference room or other large-scale scenes, you can buy a device with high output power.
3. patch interference antenna
Features:
- Easy to hide
- Suitable for concealed interference applications
- Suitable for mounting on vehicles or fixed devices
Applicable scenarios:
- Barely visible jamming equipment is required (e.g. concealed GPS jammer for vehicles).
- Portable jammers
- Applications that need to be integrated into the device
Selection proposal:
Patch antennas are a good choice if you want to jam radio signals without attracting attention, for example to prevent GPS tracking or to protect privacy. It can be cleverly concealed in the dashboard, roof or other fixtures. Have you ever bought a jammer with an internal antenna? The actual effect of this antenna is similar to the built-in antenna of the jammer.
4. yagi jammer antenna
Features:
- Strong directivity and high amplification
- Suitable for remote interference
- Consisting of several components, high interference accuracy
Applicable scenarios:
- Interference signal transmission over long distances (e.g. drone control signals)
- Interference due to obstacles
Selection proposal:
Have you ever seen a drone jammer this big? Some larger drone jammers use Yagi antennas for jamming. If your mission requires jamming radio signals over long distances or specific targets, a Yagi antenna is an excellent choice. For example, some anti-drone devices use Yagi antennas to jam the remote control signals of drones, sending them out of control.
5. whip antenna
Features:
- Omnidirectional and directional
- Suitable for mobile devices or vehicle-mounted jammer systems
- Simple structure, easy to install
Applicable scenarios:
- Interference with the vehicle's GPS signal
- Portable wireless signal jammer
- Radio interference in mobile scenarios
Selection proposal:
If you need more flexibility, a specific coverage area and the ability to adapt to interference requirements from different directions, a rod antenna is a good choice. It is often used in vehicle-mounted jammers and can effectively jam GPS, Wi-Fi, cellular signals, etc.
6. integrated interference antenna
Features:
- Hidden in a vehicle or device
- Does not impair the appearance, high aesthetics
- Provides stable interference capability
Applicable scenarios:
- Signal interference from high-end vehicles or confidential devices
- Where hidden interventions are required
- Need to install interference devices without affecting the normal appearance
Selection proposal:
Integrated antennas are ideal if you want to jam wireless signals without affecting the appearance of your device or vehicle, but still want a strong and stable jamming function. For example, some modern GPS jamming systems for vehicles use integrated antennas to ensure concealment.
How do you choose the best jammer antenna for you?
The following key factors must be taken into account when selecting a jammer antenna:
1. target frequency range
Make sure that the antenna covers the frequency band that you want to interfere with. Do you know the frequency of the signal you need to jam? If you are unsure, contact the manufacturer of the device you have purchased. If you have purchased our devices, simply contact us! For example:
- GPS interference: approx. 1.5 GHz
- Mobile radio signal interference: 800 MHz ~ 2.5 GHz
- Wi-Fi interference: 2.4 GHz / 5.8 GHz
- Drone interference: 900 MHz, 2.4 GHz, 5.8 GHz
2. interference range and strength
- Interference at close range (several meters to several tens of meters): suitable for portable or vehicle-mounted devices, usually using omnidirectional or patch antennas.
- Medium-range interference (several hundred meters): Directional or rod antennas are required.
3. antenna installation method
- Automotive applications: Omnidirectional, patch or integrated antennas are recommended.
- Fixed location: Directional or omnidirectional antennas are optional and can be aligned as required.
- Precise interference over long distances: Use a Yagi antenna or a directional antenna with high gain.
4. hidden antenna
- Low visibility: Choose between patch antenna or integrated antenna.
- There's no need to hide: use either a rod antenna or an omnidirectional antenna.
First think about your interference needs and then analyze and select the type according to your requirements! When selecting a suitable interference antenna, the frequency range, interference range, installation type and concealment must be taken into comprehensive consideration. If you need omnidirectional coverage, an omnidirectional antenna is the best choice; if you need precise interference over long distances, a Yagi antenna would be more suitable; and if you want to hide it in a low profile, patch antennas and integrated antennas are ideal solutions.
