Rundstrålande antenn DeLOCK 89495

The DeLOCK 89495 is an omni-directional antenna designed for indoor use in the ISM 433 MHz band. It provides a 3 dBi gain, a 50 Ω impedance and connects via a male SMA connector. Its compact dimensions (17 mm × 40.4 mm × 8.7 mm) and black housing make it suitable for integration into a variety of wireless devices and installations where space is limited.

Advantages

The antenna offers omni-directional radiation for consistent coverage around the installation point and a 3 dBi gain to improve short-range signal strength. The male SMA connector ensures compatibility with devices that accept standard SMA interfaces. Compact size and 50 Ω impedance make it straightforward to match common radio modules and receivers operating at 0.433 GHz.

How to use

Attach the male SMA connector to a matching female SMA socket on your device. Position the antenna vertically for typical omni-directional coverage and ensure it is mounted away from large metal surfaces where possible to avoid detuning. Use standard coaxial cabling and SMA adapters if an extension or different orientation is required.

Recommendations

For best performance, keep the antenna clear of nearby metal obstructions and locate it higher or centrally within the coverage area. Verify connector compatibility before installation and, if necessary, use a suitable SMA adapter or low-loss extension cable to retain signal quality.
