High Power 400W Signal Jammer GSM Cell Phone Signal Blocker For
Schools VSWR Protection
GW-J265DW this 400W high power signal jammer is constructed inside a special
metal enclosure prison jammers , incorporating an efficient "smart
active" cooling system with incoming air filters, which enables the
system to operate 365 days/24 Hours/7days continuously even in hot
weather. Its secure design ensures that the prison inmates and
unauthorized prison personnel cannot tamper with the safe and
continuous operation of the system.
All Cellular Mobile Devices will be totally BLOCKED, and will not
be able to receive or dial outgoing calls.
can support 4 band, 5 band or 6 band, each band output power 15W to
100W.
400W Signal Jammer Advantages:
1. VSWR protection,
When there be antenna disconnect, full system will not burn out.
