Description

“Grets” 4G Signal Jammer from BlueBird is a powerful multi-channel device for blocking wireless communication in CDMA, GSM, 2G, 3G, and 4G bands. The device is designed to neutralize signals in an indoor coverage area of 10 to 40 meters; the actual radius depends on the signal level at the point of use and other conditions. Each of the 5 channels generates 30-50 W of power, with a total output power across all channels of 150-250 W.

  • GSM / CDMA — 850-965 MHz → 30-50 W
  • 2G DCS / PCS — 1805-1990 MHz → 30-50 W
  • 3G UMTS / WCDMA — 2110-2180 MHz → 30-50 W
  • 4G LTE / WiMax2 (Europe) — 2570-2690 MHz → 30-50 W
  • 4G LTE / WiMax2 (Europe) — 2360-2505 MHz → 30-50 W

Features:

  • Multi-frequency reception and high output power for reliable blocking of communication channels.
  • Active cooling system ensures stable operation under prolonged loads.
  • Separate switches for each frequency allow flexible device configuration.
