Antenna 2.4GHz 4dBi Omni Directional & Directional versions: Flat Dipole

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.

• We have two options:
  • Omni directional version: Radiates signal with a beam of 360 degrees; also receives signal from 360 degrees around it.
  • Directional antenna: Version radiates signal to the front and back.

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: 

• IoT wireless & M2M: Bluetooth, ZigBee, and ISM. Since it is vertically polarized, it is compatible with many machine to machine communication applications, remote monitoring, and telemetry applications. 
• 2.4GHz WiFi applications: 802.11N, 802.11G, 802.11B
• Compatible with Bluetooth devices, Wireless Access Points & other wireless devices that have RP-SMA antenna jacks
• As Bluetooth antenna: Send or receive signal to devices in all directions (360-degree horizontal beamwidth)
• As client antenna: Connect to access points in any direction. Portable size: Easily fits in laptop case
• Mounts directly onto RP-SMA (female) connector of access point, wireless bridge, or client.

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 dipole antenna, as it ensures coverage equally in all directions.

SPECIFICATIONS:

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

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
• 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.
• 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.

Data Alliance's high-quality soldered terminations of RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.
