Κατευθυντική κεραία DeLOCK 89890

The DeLOCK 89890 is a directional antenna designed for indoor and outdoor use to improve reception across multiple wireless technologies. It covers frequency ranges 0.698–0.96 GHz and 1.71–2.7 GHz, has a maximum gain of 8 dBi, 50 Ω impedance and an SMA connector. With a 5 m cable and compact dimensions (229 × 237 × 50 mm), it is suitable for installations where targeted signal reception is required.

Advantages

The antenna supports a wide array of standards including GSM, UMTS, LTE, ZigBee, DECT, Z-Wave, NB‑IoT, WLAN, Bluetooth and LoRa (868 / 915 MHz). Its directional design and 8 dBi gain provide improved signal focus and reception compared with omnidirectional antennas. The included 5 m cable offers flexible placement options while the SMA connector and 50 Ω impedance ensure compatibility with common radio equipment.

How to use

Mount the antenna in the direction of the desired signal source for best performance. Connect the SMA connector to a compatible radio device or adapter with 50 Ω input. Use the 5 m cable to position the antenna optimally, avoiding large metallic obstacles and sources of interference. For outdoor installations ensure secure mounting and weather‑proofing of the connector and cable route according to local guidelines.

Recommendations

Position the antenna as high as practical and point it toward the transmitter to maximise gain effect. Verify device compatibility with SMA connector and 50 Ω impedance. For critical links, test multiple orientations and mounting locations to find the optimal placement.
