Configuring Antennas
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 the AP340 and the AP350 are adjustable, and can be
patch, directional (single-direction), and omnidirectional antennas. The type of antenna you use determines
the coverage pattern.
Single-direction Antennas
The most common external antennas are directional patch antennas that provide coverage in a single
direction. Most commonly they have a transmission pattern similar to that shown in
Based on the gain, the signal will be wide (like the low gain antenna shown on top) or narrow and long (like
the high gain antenna shown on the bottom).
Aerohive devices accommodate external antennas via coaxial jacks on the chassis (see
). These jacks are standard male RP-SMA connectors.
Coverage patterns are not perfect for these antennas and they often broadcast slightly in
directions other than the primary one. These extra "lobes" can be seen in both of the patterns
shown below.
5 GHz Antenna for
IEEE 802.11a/n
Length when fully
extended: 5 15/16”
(15 cm)
2.4 GHz Antenna for
IEEE 802.11b/g/n
Length when fully
extended: 7 7/8” (20 cm)
Generally, orient the antennas vertically for
improved radio coverage, as shown.
When mounting the AP340 on
a ceiling, orient the antennas
downward.
When mounting the device on
a wall or post, fully extend the
antennas upward and
downward.
When mounting the device
above a ceiling or on a
horizontal beam, orient the
antennas upward.
The base of the antennas hinge up to 90 degrees so that you
can orient them independently of the position of the HiveAP
chassis. The antennas also rotate in a full circle.
