Omni-directional antenna DeLOCK 12712

The DeLOCK 12712 is an omni-directional antenna designed for indoor use on the 433 MHz band. It provides a gain of -0.5 dBi with a 50 Ω impedance and comes with an SMA female connector. Its compact black housing (8 mm × 8 mm × 47.3 mm) makes it suitable for integration into compact wireless devices and installations where space is limited.

Advantages

The omni-directional pattern supports reception and transmission in all horizontal directions, while the SMA female connector ensures compatibility with many radio modules and receivers. The antenna's small size and light weight simplify installation in confined spaces or on equipment with limited mounting area. Operating at 0.433 GHz, it is suitable for common low-power wireless systems.

Suitable for

• Indoor wireless sensors and telemetry
• Remote controls and alarm systems
• IoT modules and low-power RF devices operating at 433 MHz
• Integration into compact communication equipment

How to use

Attach the antenna to a compatible SMA male connector on your radio module or receiver. Position it vertically for optimal omni-directional coverage and avoid placing it directly next to large metal objects that can detune performance. Ensure the device and antenna are powered and configured according to the radio module manufacturer's instructions before testing signal performance.

Recommendations

For best results, mount the antenna in a central, elevated position indoors and allow some clearance from metal enclosures. Verify compatibility with your 433 MHz equipment and check local regulations for allowed transmit power when used with transmitting devices.
