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


In stock
0.04 LBS
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
  • Data Alliance's high-quality soldered terminations of RP-SMA and SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.

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

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


  • Frequency Range: 2400~2483.5MHz
  • Bandwidth: 83.5MHz
  • Polarization: Linear
  • Gain: A2D2 & A2D2RA: 2dBi | A2D2v2 and A2D2RAv2:1.75 dBi | A2D2RAv3:2.15 dBi
  • V.S.W.R. (minimum): <2.5 | A2D2RAv3:< 1.5 (Lower VSWR is better <1.5 is an excellent V.S.W.R that translates to high performance.
  • Impedence: 50 Ohms
  • Operating temperature: -40 degrees Celcius to +85 Celcius
  • Vibration: 10 to 55Hz with 1.5mm amplitude 2 hours
  • ROHS 3 & REACH compliant: Antenna, cable and connector are all compliant with ROHS 3 and REACH.
