The validity of a simple formula for the level of sidelobe radiation due to profile errors in an antenna reflector has been verified by numerical evaluation of Ruze's integral. The statistical distribution of the sidelobes is discussed before the formula is applied to the practical case of large earth-station antennas. Profile errors may significantly impair the sidelobe performance of these antennas unless adequate tolerances are specified.
