The network signal is sometimes limited by space environment factors, and it may be difficult to receive the signal at the edge of the space. Therefore, the router will install an external antenna to enhance the signal transmission distance. To install the external antenna, the circuit board of the device will have an electronic switch to change the direction of operation of the signal source. In this way, existing devices can be directly upgraded, and even second-generation models can be quickly launched.

HOW is E-switch work?

E-switch practical application

The switch component is an electronic component that controls the open circuit or closed circuit of the circuit. When the switch is installed on the pcb, the direction of the signal source can be changed according to the user's needs. The Grand-tek E-Switch is mainly to change the direction of the antenna signal source. The following figure is an example when an external antenna is connected to the E-Switch, it can dominate the signal reception of this device. Such applications can not only enhance the original device signal. It can also convert the transceiver frequency, for example, LTE to WIFI.

E-Switch Advantage

• Connectors use standard products
• Cost controllable
• Grand-tek self-production group - controllable delivery time.

Vertical SMA to assemble External active model. And easy to assemble.
