This coaxial switch has the ability to re-direct the antenna circuit in a device. There are times when a weak antenna signal occurs due to physical barriers. Typically this happens when using a wireless LAN indoors. The MS-162B becomes very effective in overcoming this problem by simply connecting to an external antenna. When the primary device is plugged into the external antenna, the connector automatically switches the device’s internal antenna signal/circuit to the external antenna. When the device is un-mated it switches back to the internal antenna of the device.
