Antenne omnidirectionnelle DeLOCK 89494

The DeLOCK 89494 omni-directional antenna provides indoor support for multiple mobile and short-range wireless bands. With a gain of 2.5 dBi and coverage across 0.824–0.96 GHz and 1.92–2.17 GHz, it is suitable for GSM, UMTS and LTE reception as well as common short-range protocols. The antenna has a 50 Ω impedance and an SMA male connector, and its compact black housing (16.2 mm × 126 mm × 8.8 mm) enables easy installation in constrained spaces.

Advantages

The antenna offers multi-band operation covering lower cellular and higher short-range bands, a moderate 2.5 dBi omni-directional gain for uniform reception, standard 50 Ω impedance and an SMA male connector for wide compatibility. Its small, black form factor simplifies mounting indoors without occupying much space.

Key specifications

How to use

Connect the SMA male connector to the corresponding SMA female port on the router, gateway or radio device. Position the antenna vertically in a location with minimal metal obstruction and, if possible, near a window or higher placement to improve line-of-sight. Confirm device settings for the appropriate frequency band and test reception to find the optimal placement.

Recommendations

For best results, avoid placing the antenna directly against large metal surfaces and keep it elevated and clear of other electronic equipment. Use this omni-directional antenna when uniform 360° coverage is required rather than a focused directional link.
