Antenna 2.4GHz 2dBi Omni Directional w/ RP-SMA-male or SMA-male: Outdoor / Waterproof

$2.99

Quantity:

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

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.
Right Angle RP-SMA Connector option.
