ALLNET ALL-ANT2458-PCB Indoor Dual-Band PCB Antenna 2.4/5 GHz 2dBi Self-Adhesive

The ALLNET ALL-ANT2458-PCB is a compact, self-adhesive PCB antenna designed for indoor dual-band Wi-Fi and IoT applications. Operating at 2.4 GHz and 5 GHz with a gain of 2 dBi, this antenna provides reliable omnidirectional coverage for wireless devices such as routers, access points, and embedded systems. Its low-profile design and 3M adhesive backing allow for easy installation on walls, ceilings, or equipment enclosures.

Advantages

This antenna offers a cost-effective solution for improving wireless signal strength in confined spaces. The self-adhesive mounting eliminates the need for drilling or additional hardware, making it ideal for retrofitting or prototyping. With an IPEX (U.FL compatible) connector, it integrates seamlessly with common Wi-Fi modules and development boards.

Suitable for

• Wi-Fi access points and routers (802.11b/g/n/ac/ax)
• Bluetooth and Zigbee devices
• IoT gateways and sensors
