DeLOCK 88690 körsugárzó antenna

The DeLOCK 88690 omni-directional antenna is designed for devices with SMA connectors to receive and transmit GSM signals. It provides 2 dBi gain and vertical polarization in a compact black housing (32 × 32 × 103.3 mm), suitable for indoor and outdoor placement.

Advantages

The antenna's omni-directional pattern offers uniform coverage around the mounting point, while the 2 dBi gain balances compact size and improved signal strength. Vertical polarization ensures compatibility with most GSM equipment. The RP-SMA connector type allows easy installation on compatible devices.

Suitable for

• Extending GSM reception for routers and gateways with SMA/RP-SMA ports
• Improve mobile signal for IoT devices and modems
• Indoor and sheltered outdoor installations where compact antenna size is required

Key specifications

• Model: DeLOCK 88690
• Connector type: RP-SMA
• Antenna gain (max): 2 dBi
• Polarization: Vertical
• Dimensions (W × D × H): 32 × 32 × 103.3 mm

How to use

Connect the antenna to the device's RP-SMA/SMA connector by screwing it on until secure. Position the antenna vertically for best vertical polarization performance and place it in a location with minimal obstructions between the antenna and the signal source. For outdoor use, ensure the connector and device are appropriately weather-protected.

Recommendations

For optimal GSM performance, mount the antenna at a raised position away from large metal objects and other antennas. If signal conditions are poor, try slight adjustments to height and orientation; avoid unnecessary bends in the antenna that could affect gain.
