Antenna omnidirezionale DeLOCK 88915

The DeLOCK 88915 is an omni-directional antenna designed for devices with an SMA connector to operate in the ISM frequency band at 433 MHz. With a compact form factor (50 mm height and 8.5 mm diameter) and a 50 Ω impedance, it provides a simple solution for receiving and transmitting 433 MHz signals in applications that require vertical polarization and a modest gain of 1 dBi.

Advantages

The antenna offers an omni-directional radiation pattern with a gain of 1 dBi and vertical polarization, making it suitable for general-purpose 433 MHz links. Its SMA connector ensures compatibility with many radio modules and receivers, while the flexible design improves resistance to impacts and mechanical stress. The small size and black finish allow for easy integration into compact installations.

How to use

Connect the antenna to a device with a compatible SMA connector and position it vertically to match the antenna's polarization for optimal signal coupling. Ensure the antenna has sufficient clearance from large metal surfaces that could detune performance. The compact, flexible design allows mounting in confined spaces; secure it so it is protected from repeated heavy impacts although normal mechanical flexing is supported.

Recommendations

For best performance on 433 MHz links, place the antenna away from large metal objects and other antennas, keep it upright to maintain vertical polarization, and verify SMA connection is tight but not over-torqued. Use suitable cable adapters only if impedance and connector type match to avoid signal loss.
