Shielded band: you must know which signals you want to block before buying. Moreover, our company's GPS signal shield adopts full-band shielding. If a user wants to shield a signal, they just need to install the corresponding antenna on the machine.

Smaller GPS signal jammers must be hand-held and portable, easy to carry
  • Power supply: Hand-held GPS jammers is a built-in lithium battery. After the power is used up, it can be charged with the power adapter; the test room of the table type uses a 220V voltage power supply, and the vehicle-mounted application is usually a 12-36V voltage power supply.
  • Body size: Generally speaking, the smaller one must be hand-held and portable, relatively small in size, and easy to carry; the low-power desktop type is usually not very large in size, similar to a small notebook computer; the high-power one is not very large. It's heavy, and the towing box type is particularly large.
  • Shielding range: the shielding range is proportional to the power. In general, low-power GPS signal isolators are widely used in examination rooms. Installed in the classroom is enough, the shielding area is about 200 square meters. It can reach 300-400 meters, depending on the strength of the local magnetic field.
  • Power size: jammer is usually divided into low power, medium power, and high power, power of 3W - 100W.When we recommend users choose a GPS signal jammer, the total area to be shielded is determined.
  • Appearance: GPS Signal Jammer in appearance can be divided into an external antenna and a built-in antenna. In general, the external antenna is extended outward, because the antenna is external, so compared with the internal antenna, the external antenna takes up a lot of space. A little; Because it's just an extended antenna, the effect of the external antenna should be stable.
  • Applicable occasions: For applications related to shielding, if it is used in indoor applications, GPS signal jammers that are usually suitable for examination rooms, conference halls, offices, and other spaces are one category. Gas stations must be explosion-proof and high-temperature resistant; if it is an outdoor open area, medium-power equipment must be used to achieve suitable spacing.

valuable insights into key factors to consider when selecting a GPS signal jammer, such as the shielded band, power supply, body size, shielding range, power size, appearance, and applicable occasions. Let's delve deeper into each aspect and elaborate on their significance:

  1. Shielded Band: Understanding the signals you want to block is crucial before purchasing a GPS signal jammer. Opting for a device that offers full-band shielding ensures comprehensive coverage against targeted signals. The flexibility to install corresponding antennas simplifies the customization process based on specific user requirements.
  2. Power Supply: Different types of GPS jammers utilize varied power supply options, including built-in lithium batteries for handheld devices, standard voltage power adapters for table-top models, and voltage power supplies ranging from 12V to 36V for vehicle-mounted applications. Choosing the appropriate power supply ensures optimal performance and convenience in different usage scenarios.
  3. Body Size: The size and portability of GPS jammers vary depending on their intended use. Handheld devices are compact and lightweight, ideal for on-the-go applications. Table-top models resemble small notebook computers and are suitable for stationary use. High-power jammers may be bulkier but offer enhanced performance, while towing box types are particularly large and robust.
  4. Shielding Range: The effectiveness of a GPS signal jammer is directly proportional to its power output. Lower power devices are suitable for smaller areas such as examination rooms, classrooms, and offices, with a typical shielding range of around 200 square meters. Higher power models can cover larger areas, reaching distances of 300-400 meters, depending on local electromagnetic conditions.
  5. Power Size: GPS jammers are categorized based on their power output, ranging from low power (3W) to high power (100W). Recommending the appropriate device involves assessing the total area requiring shielding and selecting a jammer with sufficient power to meet the specific needs of the application.
  6. Appearance: The appearance of GPS signal jammers can feature either external or built-in antennas. External antennas offer stable performance but may occupy more space due to their protruding design. In contrast, built-in antennas are more discreet but still provide reliable signal blocking capabilities.
  7. Applicable Occasions: Consideration of the intended usage environment is crucial when selecting a GPS jammer. Indoor applications such as examination rooms, conference halls, and offices require devices tailored to indoor use, while outdoor settings necessitate medium-power equipment capable of withstanding environmental factors and achieving suitable coverage.
