Front-to-back ratio Front-to-back ratio In telecommunication, the term front-to-back ratio ("also known as front-to-rear ratio") can mean: The ratio compares the antenna gain in a specified direction, "i.e.", azimuth, usually that of maximum gain, to the gain in a direction 180° from the specified azimuth. A front-to-back ratio is usually expressed in dB. In point-to-point microwave antennas, a "high performance" antenna usually has a higher front to back ratio than other antennas. For example, an unshrouded 38 GHz microwave dish may have a front to back ratio of 64 dB, while the same size reflector equipped with a shroud would have a
