APX-JP-9B 9-Band Mobile Phone Signal Jammer

The APX-JP-9B is a 9-band mobile phone signal jammer for blocking mobile phone signals in meeting rooms, examination halls, prisons and other sensitive areas. It stops calls, messages and data on the covered bands so confidential discussions and examinations stay undisturbed.

Its channels cover CDMA/GSM, DCS/PHS, 3G, 4G, GPS Customization, 2.4G/Wi-Fi and 5G, with output power up to 38 dBm per channel and flat in-band response of ±0.5 dB to ±2 dB.

For meeting rooms, examination halls and prisons that need nine-band coverage with strong output power, the APX-JP-9B sits between the 8-band and 10-band models in the family.
