Antenna 2.4GHz 4dBi Omni Directional & Directional Versions

This type of WiFi antenna is called a dipole antenna, sometimes called "rubber duck" antenna.

The very low V.S.W.R of this antenna is indicative of a very efficient, high-performance antenna. Lower VSWR is better.

Compatible with Wireless Access Points & other wireless devices that have RP-SMA antenna jacks

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:

A low gain (4dBi) omni-directional antenna like this provides a strong signal in every direction Intended for short range networks: Reaches everyone within its range. If you are in a building and need to cover the rooms around you then your best options is a 4dbi dipoleantenna, as it ensures coverage equally in all directions.

The antenna exhibits stable and reliable RF performance across the 2.4 to 2.55 GHz range, with good impedance matching and controlled reflection losses. Notable operating points are observed around 2.43–2.45 GHz and 2.53–2.54 GHz, where the Return Loss improves and the SWR remains within suitable levels. Overall, the antenna provides efficient transmission and predictable behavior, making it well suited for professional applications such as 2.4 GHz WiFi, Bluetooth, Zigbee, and IoT systems.

Frequency Assessment Rating Compatible technologies
2.40–2.45 GHz Excellent ★★★★ WiFi 2.4 GHz, Bluetooth, Zigbee, Thread, IoT devices, smart sensors, industrial wireless nodes.
2.45–2.50 GHz Very good ★★★★ WiFi 2.4 GHz (upper channels), Bluetooth, industrial IoT, telemetry systems, proprietary RF links.
 

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-maleconnector 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 .
