Abstract
A large deployable antenna of 10 m maximum diameter was successfully launched and deployed in space aboard the satellite Halca in February, 1997. The main reflector is composed of a novel deployment scheme of tension truss. The parabolic surface is eventually approximated by triangular facets. The operating frequencies are 1.7 GHz, GHz, and 22 GHz. This paper describes the outline of the antenna emphasizing the measures against the cables entangling and the electrical performances.
