DeLOCK 88451 Omnidirectional Antenna

The DeLOCK 88451 is an omni-directional LTE antenna designed to connect to devices with an SMA connector to receive and send wireless signals. It offers a peak gain of 5 dBi, supports multiple frequency ranges (0.824–0.960 GHz, 1.710–2.170 GHz and 2.570–2.620 GHz), and uses vertical polarization with 50 Ω impedance. Its compact dimensions (21.5 × 21.5 × 137 mm) and black finish make it suitable for indoor or outdoor mounting where an unobtrusive omni antenna is required.

Advantages

The antenna provides uniform omni-directional coverage with a moderate 5 dBi gain, enabling improved signal strength without the need for directional alignment. Multi-band support covers common LTE and related wireless bands, simplifying compatibility with a variety of LTE devices. The SMA connection and 50 Ω impedance ensure straightforward integration with most consumer and industrial modems and routers. Compact size and black colour allow discreet installation.

Suitable for

• Improving LTE signal reception for routers and modems with SMA connectors
• Multi-band wireless setups that require coverage across 0.824–2.620 GHz ranges
• Indoor or sheltered outdoor installations where omni-directional coverage is desired

How to use

Connect the DeLOCK 88451 to the SMA antenna port of your LTE device, ensuring the connector is securely tightened but not over-torqued. Position the antenna in a location with minimal obstructions and, if possible, elevated to improve line-of-sight to nearby base stations. For optimal omni-directional performance, mount the antenna vertically so that the element orientation matches the vertical polarization.

Recommendations

Use this antenna with devices that accept SMA connectors and 50 Ω antennas. If you experience weak signal, try relocating the antenna to higher positions or near windows; avoid placing it inside metal enclosures. For outdoor exposure, verify weather protection of the installation point and any additional cabling used.
