Antenna 2.4GHz 0.5dBi Omni Directional

  • Omni directional radiates signal with a beam of 360 degrees; also receives signal from 360 degrees around it.
  • This type of WiFi antenna is called a dipole antenna, sometimes called "rubber duck" antenna.
  • The RP-SMA version is priced lower because we have an excess of stock of this version.

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 excellent low broadband VSWR at < 1.5, and impedance matching to 50 Ohm gear, makes it suitable and compliant for all the following applications:


Frequency: 2400 - 2500 MHz
Polarization: Linear Vertical
VSWR: <1.5:0
Max Power: 50W
Impedance: 50 Ω
Weight: 13g
Size: L27×W13.7×H13.7mm
Color: Black

ROHS 3 & REACH compliant: Antenna, cable and connector are all complaint with ROHS 3 and REACH.

RP-SMA and 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 and SMA are round screw-type connectors, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.
  • Composition
    • Connector Body: Brass, Gold Plated for low loss. Precision-machined.
    • 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).
  • SMA-male connector fits items that have an SMA (female) jack/connector.
  • Gender of SMA is counter-intuitive: Please observe picture & note it is correct.


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