Antenna Dual-Band Omnidirectional

Dual Band Antenna Omni Directional with RP-SMA (male) connector and SMA-male connector options (choose above)

  • Sends WiFi / wireless signal high and low enough to reach 2 levels of a building.
  • Omni dipole antenna: Radiates signal with a beam of 360 degrees; also receives signal from 360 degrees around it
  • Mounts directly onto RP-SMA-female or SMA-female connector of radio or client device
  • Bottom section of "right angle" version has articulating angle that can be adjusted to 90-degrees or other angle.
  • The versions with an all-brass base (connector section) are waterproof / weatherproof rated IP65.

Compatibility with wireless standards & applications: This omni directional dual band antenna's range of frequency band compatibility in the 2.4GHz and the 5.8GHz frequencies, its excellent low broadband VSWR at < 1.7, and impedance matching to 50 Ohm gear, makes it suitable and compliant for all the following applications:

Omni-directional direct connect antennas tuned to perform on 2.4 & 5.8 GHz networks. Vertically polarized and suitable for many of today’s machine to machine and communication applications such as telemetry, remote monitoring and mesh networking applications.

Lead-free and ROHS 3 compliant: The entire product is ROHS 3 compliant (connector and antenna).

RP-SMA and SMA Connector Characteristics:

  • RP-SMA & SMA Connector Composition: Our RP-SMA & SMA connectors are precision machined and gold-plated for low loss.
  • 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 have threads on the inside. More details regarding RP-SMA gender determination.
  • RP-SMA-male and SMA are also called "plugs" and the respective female connectors are also called "jacks".
  • 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
  • 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.

    need smaller sma antenna for a project and these work perfect
