    They are illegal in the USA, Cell Phone companies detect the signal on their network and rat you out, a local establishment here in Louisiana had one and FCC Agents along with Federal Marshalls removed the device and "Warned" the owner, you see, being a wide band jammer it blocks public service also.

    • Affected Frequency Ranges:
      -CDMA 851MHz-894 MHz 35dBm 8dBm/30KHz (min)
      -GSM 925MHz-960 MHz 35dBm 5dBm/30KHz (min)
      -DCS / PCS 1805-1990MHz 33dBm 2dBm/30KHz (min)
      -3G 2110-2170MHz 33dBm 2dBm/30KHz (min)
      -VHF 135MHz-174MHz 34dBm 5dBm/30KHz (min)
      -UHF 400MHz-470MHz 34dBm 5dBm/30KHz (min)
    • Output Power: 15 Watts
    • Power supply: AC adapter (AC220V-DC12V)
    • Shielding Radius: (2-50) meters@-75dBm (depends on the strength signal in given area

    What is this " 34dBm 5dBm/30KHz (min) " spec??? #of CW characters per (min)???
    Legality aside,
    isn’t 135-175 MHz used by commercial aircraft and in many parts of US in public ( fire , police) service?

    Even crummy porcupine "antennas" and alleged 15W output with 50 meters range should interest some of these agencies. ( Is there an external Yagi antenna outlet on it?)

    I wonder if I buy T-95 , I am sure some army would be wiling to free ship it to US, and drive it around the hood with the jammer in it , how long before federalis black SUV s shows up.

    Aren’t mutivibrators cool wideband square wave devices? Or are they using VFO's?

    That is the power referenced to one milliwatt.
    34DBM off the top of my head is 2.5W.

    Many new theaters are being built with RF shielding (prefab panels).

    There's nothing wrong with shielding your establishments against the use of cellphones. It's expensive and if you already have an established business it can be difficult. One open door and your RF proof area is now compromised.
    The use of jammers is a definite no-no and the FCC will seek the records of the company selling these items and they will locate the jammers, confiscate them, give a fact of life talk to the owner or fine them.
    As for restaurants and movie theaters. Does anybody remember when it was courteous to not talk during a movie. If in a restaurant you had to make a call or receive one the telephone was brought to you and it better be a matter of life or death. Nothing was ever that important that it couldn't wait unless it was life or death. For those reason a doctor or other health care practitioner should never go to an establishment where they cannot be contacted. The rest of us can make due without the phone for that short period of time. Jammers can exceed the area where it's supposed to be used and result in unintended loss of communications to an entire area.
    For that reason alone they are illegal and once found to be sold and shipped into the United States the companies are informed their resources here will be impounded and their ability to do business in the United States will be terminated. They will also place the import items on the impound list and have their products detained until they come and try to get them. The companies overseas doing this usually will alter their names so the contents are not obvious and will still be received by the buyer. So, it's not perfect yet but it's a start. Educating the public is a necessary step and I believe the FCC even has a toll free number to call to report an area that is being jammed.
    Have fun
