## Long description

The DeLOCK 89490 is an omni-directional antenna designed for indoor use in the ISM 433 MHz band. It operates at 0.433 GHz with a maximum gain of 2 dBi, a characteristic 50 Ω impedance and a male SMA connector. Its compact dimensions (29.4 mm × 29.4 mm × 121 mm) and single-piece polybag packaging make it suitable for adding or improving wireless links where 433 MHz coverage is required.
Advantages
The antenna provides uniform omni-directional radiation suitable for short-range indoor coverage and low-power telemetry. Its male SMA connector ensures compatibility with many radio modules and receivers that accept SMA connections. The 2 dBi gain balances modest signal reach with compact size, and the 50 Ω impedance matches standard radio equipment.
Suitable for
 Indoor ISM 433 MHz telemetry and sensor networks
 Remote controls and home automation devices operating at 433 MHz
 Integration with radio modules and receivers featuring a male SMA interface
Key specifications

How to use
Attach the male SMA connector to the compatible SMA female socket on the radio module or receiver. Position the antenna vertically for typical omni-directional coverage indoors and avoid large metallic obstructions near the antenna to reduce detuning and signal attenuation. Verify device settings to ensure operation on the 433 MHz ISM band before use.
Usage recommendations
For best performance, mount the antenna at a moderate height away from large metal surfaces and electronic equipment that may cause interference. Use in accordance with local regulations for ISM-band devices and ensure the connected radio operates within permitted power limits.
