WiFi Signal Blocker Devices for 2.4GHz and 5GHz Networks

A WiFi jammer can differ quite a bit once you look beyond the name. Frequency coverage, output power, operating range, antenna type, power source, and size all affect which wireless network blocker makes sense. This collection brings together options covering common WiFi bands such as 2.4GHz, 5.2GHz, and 5.8GHz, with both portable and desktop formats available.

Need something rechargeable for occasional use, or a stationary unit with steady AC power? Want independent switches for different frequency bands, or a simple compact setup? These details matter more than the name on the box. Check the actual specifications, coverage, and operating format before choosing the WiFi signal blocker device that matches your requirements.

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.
