Radio relay

Radio relay is a way of transmitting information from one location to another. With radio relay antennas, radio waves are bundled together with a carrier frequency and transmitted to the receiver in the microwave range (mainly between 1 and 40 GHz). Highly directional antennas are used, mounted at suitable locations so that they are able to cover large distances (quasi-optical line-of-sight connection). A typical antenna is the parabolic reflector. Highly directional antennas permit economic use of the available frequency spectrum despite large bandwidths.
