Portable RF Jammer

0.01 to 2500 MHz portable RF Jammer


Sht4-rf is a jammer device which:

  1. Emits interferences against electromagnetic fields generated by any computers within its operating range
  2. Prevents any mobile phone and radio controlled equipment from working, thanks to radio waves

Sht4-rf generates electromagnetic interference waves, on a frequency ranging from 0.01 to 2500 MHz, with a maximum output power of 35 W. Thanks to its metal casing housed inside a travel bag, it can be used without making other people suspicious.

This Jammer is designed to block radio frequencies in its field of action, preventing the use of devices that employ these frequencies. It operates in a range between 0.1 and 2500 MHz, and thanks to its power, is able to block the transmissions of micro bugs for eavesdropping, walkie talkie systems, any remote controlled equipment (and related remote controls) and the radio tools. It's able to block radio microphones or remote control devices operating at 400-450 MHz frequency band.

Thanks to its cooling system composed of fans and heat sinks, can work continuously for a long time, day and night, without overheating problems due to the intensive use. Moreover, it can also work within a motor vehicle, connecting it to the car cigarette lighter through a common adapter.

Attention: According to the provisions of the Community rules (DL 09.05.2002 n. 269), this equipment can only be purchased outside the EU, while within the territory of the EU, its sale is reserved only for members of the law enforcement.

Many European countries, ban the sale within the UE. Check the regulations in force on its own territory before proceeding with the information request.
