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.
