Swivel (Rubber) Antenna, WiFi 2.4GHz, Omni Radiation, 2dBi Gain with RP SMA Male Connector Compact Swivel "Rubber Duck" 2.4 GHz Wi-Fi Solution Engineered for space-constrained smart home hubs, compact client terminals, and localized IoT deployments, this ultra-compact 4-inch rubber duck antenna offers a balanced 2 dBi omnidirectional gain across the 2.4 GHz spectrum. Its integrated articulating swivel joint supports 90° tilting and 360° rotation, permitting easy vertical alignment to bypass nearby physical blockages. Housed in a durable TPE radome, the antenna terminates in a standard direct-mount RP-SMA Male terminal connector.
