AELW011 433 MHz Right-Angle SMA Male Omni-Directional Rod Antenna for 423–443 MHz ISM IoT

AELW011 is a connectorized 433 MHz right-angle SMA rod antenna intended for designers who need a compact, ready-to-use radiator for the 423–443 MHz sub-GHz ISM band. The antenna integrates a linear omni radiator within a 106.5 × 18.5 mm black whip attached to a right-angle SMA male base, enabling the connector to mount flush on an enclosure wall or metal cabinet while the antenna body remains vertically upright. This geometry saves radial space around the connector and reduces the chance of impact or obstruction in dense racks and cabinets.

Electrically, AELW011 delivers a technical operating band of 423–443 MHz with 50 Ω input impedance, max VSWR 2.5:1, peak gain −2.11 dBi and efficiency up to 38.37%. The omni-directional radiation pattern and linear polarization support arbitrary device orientation, which is essential in real deployments where node orientation cannot be controlled, such as distributed IoT nodes, smart-city sensors and building security devices.

The antenna is designed as a lightweight, low-profile and rugged product, with environmental ratings of −40…+85 °C operating and storage, and 10–70 % RH, making it suitable for both indoor and outdoor applications in industrial and municipal environments. The standard SMA-M connector provides a familiar 50 Ω interface for RF modules, radios, meters and gateways, minimizing RF integration risk and avoiding custom matching networks. For purchasing teams and project owners, AELW011 offers a standardized mechanical and RF platform that can be re-used across multiple 433 MHz product variants with minimal redesign and consistent RF performance.

Package Included: 1 x swivel whip antenna
