Multiservicios de Radiodifusion of Mexico City has installed a two-hop microwave link to transport one video signal at a distance of 20 kilometers.
The links , which are installed in Mexico, are used to transport a video and two audios from a mobile unit to a relay point at a distance of up to 20 kilometers, from which a second link retransmits the signal to the studios 7 kilometers away.
The link was configured using two TVLINKs in series. The mobile unit transmitter was mounted on a turntable platform which can be pointed in both azimuth and elevation to the Repeater. The repeater input antenna is also mounted on a rotatable platform which allows pointing of the antenna by remote control.
The second link has fixed antennas at a height of 20 meters. Multiservicios designed, fabricated and installed the remote-controlled movable platforms, allowing the mobile station to relay signals at distances of up to 20 kilometers.
Mr. Jesus Navarro of Multiservicios stated that “the equipment supplied by Cable AML has made it possible to deliver reliable service at a significantly smaller cost than with any other solution.”
