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

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.
  • Right Angle RP-SMA Connector option.


All of our antennas pass QC test before we ship them.
