Vsesmerna antena DeLOCK 89437

The DeLOCK 89437 omni-directional WLAN antenna connects via an SMA plug to send and receive wireless signals across common 2.4 GHz and 5 GHz Wi‑Fi bands. It is compact, rotatable on a flexible joint and intended to improve wireless connectivity for devices with an SMA antenna port.

Advantages

The antenna supports both 2.4–2.4835 GHz and 5.15–5.7250 GHz frequency ranges and offers moderate gain (1.5 dBi at 2.5 GHz and 2.1 dBi at 5.7 GHz) while maintaining a 50 Ω impedance. Its SMA plug connector and rotatable flexible joint allow simple attachment and positioning. The device is small (approx. 108 mm with joint, 82.5 mm without) and operates in a wide temperature range (-20 °C to 65 °C).

Suitable for

• Enhancing Wi‑Fi reception for routers, access points and USB Wi‑Fi adapters with SMA port
• Use in environments requiring both 2.4 GHz and 5 GHz connectivity (IEEE 802.11 a/b/g/n/ac/h)
• Temporary or permanent installations where a compact, rotatable external antenna is needed

• Dimensions: approx. 108 mm length with flexible joint, 82.5 mm without; diameter 7.8 mm (peak), 10.0 mm (SMA)

How to use

Align the SMA plug with the SMA socket on your device (router, adapter or access point) and screw the connector in place by hand until secure; avoid overtightening. Adjust the antenna angle using the flexible joint to find the best orientation for signal strength. Use the device in accordance with the host equipment’s installation and safety instructions.

Recommendations

Install the antenna in a clear position away from large metal objects and other antennas for optimal reception; if multiple antennas are used, maintain appropriate spacing to reduce interference.
