AM FM Radio LoJack Prison Cell Phone Jammers 300 W VSWR Protection
Prison Jammer Introduction:
SIX band 300W GW-J260D will jam GSM, CDMA,DCS, PCS,WCDMA,3G, UMTS, Walkie talkie.
This cell phone prison jammer can keep you from being tracked by cell phone signal tracking systems. It is also good for schools, churches, conference rooms, hospitals and any other place that cell phones may be cause a distraction or interference.
RF Jammers are used to block radio signals. In a prison, RF Jammers can stop cell phones from getting service by severing the link between the cellular phone and the local wireless phone carrier with signal jamming. Signal jamming can work in one direction with a directional antenna, or in all directions with an omni-directional antenna to block radio signals, and prevent cell phone service.
Prison Jammer Features:
1. Max 300watts total RF output power.
2. Stable capability, cost-effective choice
3. Different frequency band can be controlled independently by single switches;
4. Power Amplifiers protection design ensures the working reliability of the device.
