As anyone who has administered a WLAN system knows, configuring the antennas correctly at the outset can save you lots of trouble. The external antennas on many Aerohive devices are adjustable, and can be patch, directional (single-direction), and omnidirectional antennas. The type of antenna you use determines the coverage pattern.
Aerohive devices accommodate external antennas via coaxial jacks on the chassis. These jacks are standard male RP-SMA connectors.
You typically orient omnidirectional antennas vertically, positioning them on all devices in the same direction. Omnidirectional antennas create coverage areas that can be toroidal (doughnut-shaped) or cardioid (heart- or plum-shaped), broadcasting to the sides much more effectively than up or down, as shown below. In general this is good for most office environments because you have large flat floors. However, it can be a problem in environments with high ceilings.
