Antenna Omni Directional w/ RP-SMA-male or SMA-male

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:

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
