Proper Orientation of Wireless Antennas

August 8, 2011 7:00 am

In order to get the best performance out of your Monnit WIT Wireless Sensors, it is important to note proper antenna orientation and sensor positioning. Antennas should all be oriented in the same direction, pointing vertically out of the sensor. If the sensor is mounted flat on it’s back on a horizontal surface, you should bend the antenna as close to the sensor housing as possible giving you the most amount of antenna pointing vertical. You should make the antenna wire as straight as possible, avoiding any kinks and curving of the wire.

For optimum signal strength determine the height at which the majority of your sensors will be mounted at and position the wireless gateway at the same height. The sensor signal strength will reduce if the sensors are positioned higher than the wireless gateway. Also sensors should be at least 3 feet away from each other and the wireless gateway to function properly.

Correct Antenna Orientation

Antennas should all be pointing vertically and devices should be at least 3 feet apart.

Incorrect Antenna Orientation

Antennas should not be pointing vertically and horizontally, and devices should not be closer than 3 feet.

Incorrect Sensor Positioning

Sensors should not be mounted high with wireless gateways mounted low. Also, avoid positioning sensors or gateways on the floor.

So remember, when placing your wireless sensors, antenna orientation is critical to reliable performance of your wireless sensors. For more information and guides on using your wireless sensors visit www.monnit.com/support/.
