Omni-directional antenna DeLOCK 88790

The DeLOCK 88790 is an omni-directional GSM/UMTS/LTE antenna with a 50 Ω impedance and vertical polarization. It covers frequency ranges 0.79–0.87 GHz, 1.71–1.88 GHz and 2.50–2.69 GHz with a maximum gain of 2.5 dBi and compact dimensions of 10 x 10 x 137.1 mm, allowing installation in limited spaces. The antenna is intended for connection to devices with an SMA interface to receive and transmit cellular signals.

Advantages

The antenna offers omni-directional coverage for consistent signal reception from multiple directions, a moderate gain of 2.5 dBi suitable for indoor and near-outdoor applications, and a slim white housing that fits into confined installations. Its 50 Ω impedance and vertical polarization make it compatible with standard GSM/UMTS/LTE equipment that use SMA connectors.

Key specifications

How to use

Attach the antenna to the GSM/UMTS/LTE device using the SMA connector, ensuring the connector is tightened securely but not over-torqued. Position the antenna vertically for optimal vertical polarization alignment. Place the antenna in a location with the least obstruction possible to improve signal strength. Check device settings and signal indicators after installation to confirm proper operation.

Recommendations

For best performance, mount the antenna away from large metal objects and sources of interference. If outdoor reception is required, use an appropriate outdoor-rated mounting and sealing solution; the antenna itself is compact and intended primarily for installations where space is limited.
