Omni-Directional 2.4GHz WiFi Antennas
Antenna 2.4GHz 2dBi Omni Directional w/ RP-SMA-male or SMA-male: Outdoor / Waterproof
Weatherproofed
antenna
for outdoor applications: All options on this page are waterproof / weatherproof.
Bottom section of
antenna
: We have two options: Fixed-straight and 90-degree right-angled bottom section.
2dBi
omni directional
radiates WiFi / wireless signal to high & low elevations in local area
The 2.15 dBi version (SKU A2D2RAv3) is the best value:
A very high-performance antenna with VSWR of less than 1.5 (lower is better -
Read about VSWR
).
This version is 110mm long.
All versions on this page are 1/2 wave
dipole antennas
Compatible with
Wireless Access Points
& other wireless devices that have
RP-SMA antenna jacks
Omni antenna
: Radiates signal with a beam of 360 degrees;
also receives signal from 360 degrees around it.
This type of
omni-directional antenna
is called a
dipole antenna
, sometimes called "rubber duck"
antenna
.
Compatibility with wireless standards & applications
: This
omni directional antenna's
range of frequency band compatibility in the
2.4 ~ 2.5GHz frequency band
range
, its its
low broadband VSWR
, and
impedance matching to 50 Ohm gear
, makes it
suitable and compliant for all the following applications
:
IoT wireless
&
M2M
:
Bluetooth
,
ZigBee
, and
ISM
. Since it is
vertically polarized
, it is compatible with many machine to machine communication applications,
remote monitoring, and telemetry applications.
2.4GHz
WiFi applications:
802.11N, 802.11G, 802.11B
As client antenna:
Connect to access points in any direction. Portable size: Easily fits in laptop case
As
access point antenna
:
Provides signal to clients in all directions (360-degree horizontal
beamwidth
)
Mounts
directly onto
RP-SMA (female) connector
of
access point
,
wireless bridge
, or client.
See image of radiation pattern of the
2dB omnidirectional antenna
among images above.
A low gain (2dBi)
omnidirectional antenna
like this provides a strong signal in every direction (including vertically)
Intended for short range meshed networks and reaches everyone within its range.
If you are in a building and need to cover the rooms around you then you are better off using a 2dbi dipole
antenna
, as they make sure you cover everyone equally
in all directions

RP-SMA Connector Characteristics
:
RP-SMA = Reverse Polarity SMA. Also known as SMA-RP, SMA-R, SMA RP, SMA R.
RP-SMA and SMA gender is counter-intuitive
: Please observe picture & note it is correct. The gender is referring to the pins inside-not the threads. RP-SMA male
has threads on inside.
More details regarding RP-SMA gender determination
.
RP-SMA-male and
SMA
is also called "plug" and the respective
female connectors
are also called a "jack."
RP-SMA is a round screw-type connectors, with medium-sized, threaded coupling connectors that are rated for
frequencies
from the lowest (DC) up to 18GHz.
Composition
Center Contact: Beryllium Copper,
Gold Plated
Crimp Ferrule: Copper, Nickel Plated
Insulators: PTFE
We offer an
RP-SMA wrench
to assist in installing antennas, cables and adapters with SMA or RP-SMA connector(s).
RP-SMA-male
connector
fits items that have an
RP-SMA (female) jack/connector
.
