¶ General Description
The Oscar 18 is a compact, plastic-enclosed directional Yagi antenna covering a wide range of commonly used cellular, Wi-Fi and LPWAN frequencies from 600–6000 MHz. Its UV and water-resistant radome, together with flexible wall or bracket mounting options, makes it well suited to fixed indoor and outdoor installations.The directional Yagi design focuses the signal towards the required coverage area, helping to improve transmission and reception where additional signal strength or a more focused wireless connection is required. The antenna provides an average gain of 7 dBi and 77% efficiency.
Typical applications include remote monitoring and telemetry, industrial and utility communications, transportation systems, IoT gateways, security and surveillance equipment, wireless networking, and other fixed installations requiring reliable wideband connectivity.
¶ Key Features
- Supports 5G NR, 4G LTE, 3G UMTS and 2G GSM
- Supports dual-band Wi-Fi, LPWAN and IoT technologies
- Directional Yagi design with 6 dBi gain
- UV and water-resistant radome for outdoor installation
