Oscar 20A5G / 4G / LoRa / Sigfox / Bluetooth / Zigbee Directional Yagi Antenna

The Oscar 20A antenna is a high gain, wide frequency range antenna for connectivity in remote environments where a point-to-point link is the only effective method of communication between equipment and single cell site.

It is recommended to be used in fixed locations where the base station direction is known.

Designed for indoor or outdoor environments the antenna is supplied with a hinged mounting bracket and 5 meters of cable with an SMA male termination (The antenna has an SMA Female connector).

The advantage of using a yagi type antenna is to improve performance over omnidirectional antennas whist keeping the small size.

See the Snyper cellular signal tester for a tool to locate the best base station in your area.

Spectral Frequency Diagram

The Spectral View Diagram visually describes the performance of the antenna from 400 MHz to 6000 MHz. Key frequencies are marked highlighting the technology used and the colour represents the performance at that frequency taking in to consideration the VSWR and radiated efficiency of the antenna.

Green is considered a suitable band, amber is adequate in good signal conditions and red is likely to be unsuitable.
