JAMMER JO3-RADIO blocks cellular frequencies up to 3G, as well as VHF-UHF radio frequencies, while being hidden inside a discreet briefcase, defined also as “hidden jammers”.

Portable Jammers, typically, present three problems:

  1. Limited output power, as well as the range that the jammer can cover;
  2. Portability: is it really as hidden as possible? Can you really carry it everywhere, in a practical way?;
  3. Limitation on the number of bands jammed.

Our JAMMER JO3-RADIO finally overcomes all these issues! The output power is that of a desktop Jammer, and given the fact it’s concealed in a briefcase, it is as discreet and undetectable as you can get! Last but not least, this portable jammer limits the same range of bands as a desktop jammer!
Unquestionably, this jammer is the best solution to protect your privacy on the go.

What is the purpose of this Jammer?

  1. It prevents cell phones from sending a signal within the indicated range, making it great for meeting rooms or places where cell phone use is prohibited;
  2. It stops bugs from transmitting at these frequencies, therefore completely nullifying them.
