Antenna 9dBi Bluetooth WiFi 2.4GHz Omnidirectional w/RP-SMA 2400MHz Alfa ARS-N19

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 (Data Alliance part# A5)

• 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:

• IoT wireless & M2M: Bluetooth, ZigBee, Wi-Fi HaLow 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, 802.11AH
• 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.

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

The VNA chart shows that the antenna is well-matched at 2.431 GHz, with a return loss of –19.68 dB and a near-optimal SWR (~1.25:1). The Smith chart indicates an impedance close to 50 ohms, confirming efficient power transfer at this frequenc.

The chart shows that at 2.431 GHz, the antenna achieves a return loss of –17.90 dB and an SWR of 1.292, indicating low signal reflection and good impedance matching. The multiple dips in the SWR curve suggest the antenna may support multiband operation, with strong performance particularly in the 2.4 GHz ISM band.

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

RP-SMA Connector Characteristics:

• RP SMA Characteristics and Key Information
• RP SMA Connector Materials 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 .
