Identifying Array Antennas

What are they?


An antenna array is a group of two or more directional (usually panel style) antennas that are grouped together to form an Omni directional signal. Many times an RF splitter is used to connect the multiple antennas to a single access point or WiFi amplifier.

 

The benefit of using an antenna array over a single Omni directional antenna is that the antenna array provides radiation patterns that a single Omni antenna would not. Many times antenna arrays provide greater coverage than a single Omni antenna could.

Where Would You Use Them?


Antenna arrays are used in outdoor point-to-multipoint applications. L-com's antenna arrays are available in 90° (4 panels), 120° ( 3 panels), and 180° (2 panels) configurations and include appropriate splitter and cables. Additionally, these antenna arrays feature zero to 20° down tilt capability to compensate for the geography of the installation location. This helps ensure maximum wireless signal coverage in the service area.

 

 

Antenna Array Configurations Available

 

 

Antenna Arrays with four 90° sectorial antennas Antenna Arrays with four 90° sectorial antennas
Antenna Arrays with three 120° sectorial antennas Antenna Arrays with three 120° sectorial antennas
Antenna Arrays with two 180° sectorial antennas Antenna Arrays with two 180° sectorial antennas
 

All sectorized omni array configurations are designed to all-weather operation. They feature both heavy-duty polymer antenna radomes and stainless steel mounting systems.
