The 2J672B dual band WiFi stud mount antenna is a durable Wi-Fi antenna with stable performance across both 2.4 and 5 GHz Wi-Fi bands. When mounted on a 300 x 300 mm groundplane the antenna has a stable radiation pattern and omnidirectional gain across all bands ensuring consistent and reliable reception and transmission.

The IP67 and IP69 ingress ratings provide this compact antenna with maximum protection against dust and water penetration, with IK09 and IK10 variants possible to add an extra level of anti-vandal security, with high impact resistance.

This stud mount antenna comes with low loss cables thread through a single mounting hole for easy installation. Cables and connectors can be customized to specific requirements. A truly versatile antenna solution allowing to change (other technologies) or remove antennas and its respective cable to satisfy your end application.
