Write a Review

High-gain 806~960 MHz 15dBi Yagi antenna

Overview

This high-gain 15 dBi Yagi antenna is designed for long-range directional communication in the 900 MHz ISM band, covering applications between 806 MHz and 960 MHz. Its narrow beamwidth and high front-to-back ratio make it ideal for point-to-point RF links, base station access, and cellular signal enhancement, especially in rural or obstructed environments.

TEST RESULTS for FREQUENCY RANGES:

report antenna

The antenna exhibits stable performance across the 884 to 929 MHz frequency range, with consistent impedance matching throughout the band. S11 measurements show VSWR values ranging approximately from 1.50 to 1.71, with the best matching point around 915 MHz, where the Return Loss reaches about −14 dB. This behavior ensures efficient power transfer with controlled reflection losses, making the antenna suitable for cellular, IoT, and sub-GHz wireless applications.

Frequency range Assessment Rating Compatible technologies
0.884–0.929 GHz Good   ★★★ Cellular 900 MHz bands (GSM/EDGE 900), LTE Band 8, private and regional sub-GHz cellular systems, NB-IoT / LTE-M deployments near 900 MHz, ISM/IoT links around 915 MHz, UHF RFID systems (regional 860–960 MHz), and industrial telemetry and monitoring applications.
Stable and predictable impedance behavior across the band, with VSWR values maintained approximately between 1.50 and 1.71. A clear matching improvement is observed near 915 MHz, where Return Loss reaches approximately −13.9 dB, ensuring reliable power transfer with controlled reflection levels for sub-GHz wireless systems.
