Buy GPS Jammer for L1, L2, L3, L4 and L5 GPS Signals

Price is only part of the buying decision; frequency coverage also matters. GPS uses several signal bands, each with different applications:

  • L1 (1575.42 MHz): Standard GPS positioning and navigation.
  • L2 (1227.60 MHz): Precision positioning and ionospheric error correction.
  • L3 (1381.05 MHz): Nuclear event detection systems, rather than routine civilian navigation.
  • L4 (1379.913 MHz): A research frequency studied for ionospheric correction.
  • L5 (1176.45 MHz): Safety-of-life navigation, including aviation.

Not every GPS jammer supports all five bands. Some models list GPS frequencies only, while others also specify cellular or WiFi bands, these additional frequency bands mean broader signal coverage. In addition, antenna design, power configuration, and device form factor also merit attention, as these details help distinguish the characteristics of different GPS tracker blockers.

Important things

1.Please install the antenna before using the signal jammers

2.Most Portable cell phone jammers have dip switches on the side. After turning on the main power switch, activate the dip switch—the red or green light will indicate it's on. Each switch controls a specific signal (Refer to the frequency table on the packaging for details).

3.Avoid using the jammer while charging.
