Directional parabolic antenna JRMC-680-10/11, created by Jirous company, has been adapted to work in the 10 and 11 GHz band, for use with Mimosa B11 radio. With JRMC 680 you can set up a very efficient point-to-point connection. The device is characterized by a narrow main beam, having a width of about 3°, which allows to avoid many interferences caused by other transmissions. The time frame, which allows for long-distance connection has width 680 mm and gain of 35 dBi.
It has an antenna with a deep reflector and a massive handle. The antenna is supplied with a bracket allowing easy mounting on a pole. The bracket can be installed separately, then you can simply hang the antenna with the microwave unit in it. The bracket allows precise adjustment in both directions. Mounting on the right and left side is possible.

A wifi antenna is a device that converts electromagnetic waves into an electrical signal or vice versa. The antenna can be used to improve signal quality and increase data transfer rate.
The best one is to mount the bracket first, and then using two screws the antenna.
