Abstract: The invention relates to a base that includes a unit for osseous attachment onto a tibia, and a plate having posterior, anterior, medial and lateral edges; a posterior pin and an anterior pin having a posterior flat section and an anterior flat section; two posterior lugs protruding above the plate and arranged on the posterior edge of each side of the posterior pin; and two anterior lugs arranged on each side of the anterior pin. The posterior flat section and the anterior flat section are arranged so as to simultaneously engage with the insert. Each posterior tab includes a support extension for inserting, in an anteroposterior direction, a complementary support tab of the insert. Each anterior lug includes a unit for snap-coupling the insert onto the base.

Abstract: A protective ballistic radome for a satellite antenna which can turn about an axis of rotation, has: a circular support in the form of a ring, having an axis of revolution RR'to coincide with the axis of rotation, with the circular support having a lower base and an upper part in planes respectively parallel and perpendicular to the axis RR', an annular groove, having an axis of revolution that coincides with the axis RR', opening onto the upper part of the circular support, a set of n contiguous walls having upper ends and lower ends in planes that are respectively parallel and perpendicular to the axis RR?, the walls having their lower ends inserted into the annular groove of the circular support in order to form a ballistic wall in the form of a tube of circular section, having the same axis of revolution RR', about said satellite antenna.
