Choosing the Right Signal Jammer
Before purchasing a signal jammer, it's crucial to consider two key factors:
  • Frequency Compatibility: Ensure the jammer covers the specific frequencies you need to block
  • Power Requirements: Match the jammer's power output to your local signal strength conditions
Portable jammers typically output 0.5-1 watt per band. In areas with strong signals, the jamming radius may be reduced to as little as 0.5 meters.
