DeLOCK 88428 omnidirectional antenna

The DeLOCK 88428 is an omni-directional LTE RP-SMA antenna with a flexible joint, designed to connect to devices with an SMA/RP-SMA connector to improve cellular signal reception and transmission. It covers multiple frequency bands (0.79–0.96 GHz, 1.71–1.88 GHz and 2.5–2.6 GHz), has a vertical polarization, 50 Ω impedance and a gain of 2.5 dBi. The antenna is compact, measuring 197.1 mm in height and 28 mm in diameter, and comes in black.

Advantages

The antenna’s omni-directional pattern provides uniform reception from all directions without manual aiming, while the flexible joint allows easy adjustment of the antenna angle. Its multi-band capability supports common LTE and cellular bands, and the 50 Ω impedance with RP-SMA compatibility ensures straightforward connection to many LTE routers, modems and gateways. The compact size simplifies installation in limited spaces.

How to use

Attach the antenna to your LTE device’s RP-SMA or SMA connector by screwing it in securely. Adjust the flexible joint to set the antenna to the desired angle for optimal reception. Place the antenna in a location with minimal obstructions and away from large metal objects for best performance. Confirm your device is compatible with the antenna’s impedance and connector type before connecting.

Recommendations

For stable reception, mount the antenna vertically when possible and avoid placing it near other wireless antennas that could cause interference. Periodically check the connector for tightness and corrosion if used in humid environments.
