Antenna 2.4GHz OmniDirectional 2.5dBi Weatherproof
Very compact, miniature omnidirectional antenna for WiFi, Bluetooth and ZigBee: 2.4GHz applications. Screw-Mount / "Through-hole mount" on back of antenna.
Compact, cylinder-shaped antenna for band 2.4-2.5 WiFi / WLAN / Bluetooth / Zigbee frequencies. Diameter of 22mm and height of 22mm: This antenna will fit comfortably on to most surfaces.
- Mount on any panel or board that you can drill a hole through, such as a ceiling panel, wall or drywall.
- Easily mounts in a ceiling tile, by drilling a hold in the tile of 11mm diameter (plus or minus 0.8mm). Antenna has a nut and washer to mount the antenna on a ceiling mount.
- Threaded part of mount is 8mm long. Panel-Hole Cutout for Through-Hole Stud-Mount: Diameter 11mm plus or minus 0.8mm. The thread is M11*1.0P
- Mount on ceiling or wall panel so that the antenna faces down from the ceiling, or horizontally from the wall.
- Can be mounted securely inside or outside, with its 8mm long screw thread
- Supplied with a 10cm cable to allow flexible mounting positioning
Compatibility with wireless standards & applications : This omni directional antenna's range of frequency band compatibility in the 2.4 GHz frequency band range, its very low broadband VSWR at < 2.0 (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 a laptop case.

TEST RESULTS for FREQUENCY RANGES:
The antenna exhibits stable and well-optimized RF performance across the 2.4 GHz band, with good impedance matching throughout the entire operating range. Its best performance occurs around 2.50 GHz, where a Return Loss of approximately –24.8 dB and an SWR close to 1.12:1 are achieved, indicating highly efficient power transfer and minimal reflection losses. Across the rest of the band, the behavior remains reliable, making the antenna well suited for wireless applications such as WiFi, Bluetooth, Zigbee, and IoT in both commercial and industrial environments.
| Frequency range | Assessment | Rating | Compatible technologies |
|---|---|---|---|
| 2.40–2.42 GHz | Very good | ★★★★ | WiFi 2.4 GHz, Bluetooth (Classic/LE), Zigbee, Thread, 2.4 GHz proprietary IoT links. Return Loss: –13.7 dB | SWR: 1.5:1 |
| ~2.50 GHz (best point) | Excellent | ★★★★ | WiFi 2.4 GHz (upper channels), Bluetooth, Zigbee/Thread, industrial IoT and telemetry systems. Return Loss: –24.8 dB | SWR: 1.12:1 |
Vandal prone environments demand tough equipment that will resist excessive force upon them: Commonly used in a host of WiFi applications in demanding environments: Vandal prone areas, outdoors and harsh weather condition locations.
Waterproof /weatherproof: Totally sealed IP65 casing prevents risk of water ingress. Includes rubber O-ring (black) that totally protects against ingress of water or dirt.
- Mounts directly onto RP-SMA(female) connector of access point, bridge, USB WiFi adapter, or booster. See other magnetic bases that fit this antenna and have antenna cables with other types of connectors .
