Difference between built-in antenna and external antenna of smart jammer

Difference between built-in antenna and external antenna of smart jammer

  • 2022-05-24

The smart jammer with built-in antenna is compared with the external antenna shield. From the perspective of external structure, the built-in antenna smart jammer integrates the transmitting antenna, power supply and heat dissipation fins into a more beautiful, plug and play external plastic shell, without complex antenna connection and plug-in power supply. It is very suitable for applications in some frequently mobile fields, such as school examination rooms, conference rooms and confidential places.

The external antenna smart jammer shell is a metal paint shell, which combines the shielding module with the shell to make full use of the shell to achieve good heat dissipation effect. The power supply of the external mobile phone signal shielding device is separated from the host, which will not add additional burden to the host and can work stably for a long time. The antenna smart jammer is more suitable for churches, troops, prisons, detention centers and other fixed places that need continuous and stable work.
