Remote Antenna Placement
• Place and align the antenna in a way that the Wi-Fi
signal does not interfere with many obstacles.
• Make sure that the antenna is installed perpendicular to
the surface for a good Wi-Fi signal.
• The antenna has a strong signal transmission and
reception from the side. See figure below. Position the
sides of the antenna towards the device it is
communicating with (e.g WiFi Node).
