Omni Directional Antenna w/ RP-SMA
Omni dipole antenna: Radiates signal with a beam of 360 degrees; also receives signal from 360 degrees around it.
- As client antenna: Connect to access points in any direction. Portable size: Easily fits in a laptop case.
- As access point antenna: Provides signal to clients in all directions (360-degree horizontal beamwidth)
- Mounts directly onto RP-SMA (female) connector of access point, wireless bridge, client, or booster
- Bottom section of antenna has hinged joint that bends up to 90-degrees. Can be used either straight or with joint-bend.
- Radiates WiFi / Bluetooth / wireless signal high and low enough to reach 2 levels of a building.
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 < 1.6, 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 a laptop case.
