Antenna 2.4GHz 9dBi Omni-Directional WiFi w/ RP-SMA-male connector

  • Omni Directional Antenna with articulating RP-SMA (male) connector for 2.4GHz WiFi / wireless networks, Bluetooth, Zigbee. Option: This antenna combined with magnetic mount.
  • This is a very special low-price offering of a very high quality antenna, due to Data Alliance having a large overstock of inventory of this antenna.   Alfa part # ARS-N19.

  • Compatible with Wireless Access Points & WiFi USB adapters & devices that have RP-SMA antenna jacks.

Omni directional dipole antenna: Radiates signal with a beam of 360 degrees; also receives signal from 360 degrees around it.

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 very low broadband VSWR at < 1.5 (lower VSWR is better), and impedance matching to 50 Ohm gear, makes it suitable and compliant for all the following applications:


2400~2500 MHz


50 Ω




9 dBi





Operation Temperature


Storage Temperature




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

Mounts directly onto RP-SMA(female) connector of access point, bridge, USB WiFi adapter, or booster

See other magnetic bases that fit this antenna and have antenna cables with other types of connectors

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: 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.
  • Articulating (Bendable) Right Angle: This antenna can be angled up to 90 degrees (articulating right angle) or positioned straight. The articulating (bendable) right-angle isn’t weatherproof: Water can seep into the angled part of the antenna. Articulating right-angle antennas are therefore recommendable for indoor use or protected outdoors, i.e. under an eave. If you need a weatherproof dipole antenna, you should choose either a straight dipole or one with a fixed right angle. See our weatherproof antennas .


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