Antenne omnidirectionnelle DeLOCK 12695

The DeLOCK 12695 omni-directional antenna provides a compact, easy-to-install solution for devices operating in the 0.433 GHz frequency band. With a maximum gain of 2 dBi, vertical polarization and a nominal impedance of 50 Ω, this antenna is intended for use where a uniform radiation pattern around the antenna axis is required. The antenna measures 40 mm in height with a diameter of 2.2 mm and uses an N-type connector for a reliable electrical and mechanical connection. The product is delivered in a box to simplify storage and transport.

Advantages

The omni-directional design offers consistent coverage in horizontal planes, reducing the need for precise aiming. Its 2 dBi gain balances modest signal improvement with a compact form factor. Vertical polarization ensures compatibility with many wireless devices and installations that use the same polarization standard. The N-type connector provides a secure connection and straightforward integration with compatible equipment.

Suitable for

• Short-range telemetry and sensor networks operating at 433 MHz
• Wireless remote controls and alarm systems using 0.433 GHz
• Prototyping and test setups requiring a compact omni-directional antenna
• Extensions or replacements for devices with N-type antenna ports

How to use

Connect the DeLOCK 12695 antenna to a compatible N-type socket on the device, ensuring the connector is tightened to provide a secure mechanical and electrical contact. Position the antenna vertically to maintain the intended polarization and omni-directional coverage. For devices mounted in enclosures or on masts, route the antenna so it remains unobstructed by metallic structures that could alter the radiation pattern. Check device transmitter/receiver settings and local regulations for operation at 0.433 GHz before use.

Recommendations

For optimal performance, keep the antenna clear of large metal surfaces and other antennas; maintain the vertical orientation during operation. If longer-range coverage is required, consider system-level changes such as higher-gain antennas or adjustments to transmitter power within legal limits. Regularly inspect the N-type connector for corrosion or damage and tighten as necessary to preserve connection quality.
