Rondstraalantenne DeLOCK 89491

The DeLOCK 89491 is an omni-directional indoor antenna designed for GSM, UMTS, LTE and WLAN 2.4 GHz applications. With a compact form factor and 50 Ω impedance, it supports multiple frequency bands (0.824–0.96 GHz, 1.92–2.17 GHz and 2.4–2.5 GHz) and is compatible with Bluetooth, ZigBee, DECT and Z-Wave devices. The antenna uses an SMA male connector and provides up to 2 dBi gain, making it suitable for improving wireless link stability in constrained indoor environments.

Advantages

The omni-directional radiation pattern offers uniform coverage around the antenna while the 2 dBi gain balances range and compact size. Multiple supported frequency ranges allow a single antenna to serve GSM, UMTS, LTE and 2.4 GHz wireless protocols. The SMA male connector and 50 Ω impedance ensure compatibility with a wide range of routers, gateways and wireless modules. Its small black housing enables discreet indoor installation.

How to use

Connect the DeLOCK 89491 to the SMA port of your router, gateway or wireless module. Position the antenna vertically in an indoor location with minimal metallic obstructions and at a moderate height to achieve more uniform coverage. Verify device compatibility with a 50 Ω antenna input before installation. After connection, test signal strength and adjust placement to optimize reception for the intended devices and frequency band.

Recommendations

For best results, place the antenna away from large metal surfaces and electronic equipment that can cause interference. If coverage is insufficient, try relocating the antenna or using multiple antennas for broader indoor coverage. Ensure the connected device supports the antenna's frequency ranges and SMA interface.
