A telecommunications antenna is provided with a reflector having a semi-offset geometry, a feed mounted on a feed source rigidly fixed to the reflector, an antenna pedestal for supporting the reflector and the feed. Positioning of the feed is such that, in respect of a reflector illumination half-angle .beta. as seen from the feed such that 45.degree.<.beta.<55.degree., the offset angle .alpha. (angle between the focal axis .DELTA..sub.Foc and the median ray of the total beam which is emitted by the feed and illuminates the reflector) is 25.degree.<.alpha.<35.degree., the antenna mount being of the azimuth-elevation type known as an az-el mount.
