A parabola antenna is provided to extend a lifespan by forming a reflector having a through-hole formed on a solid parabolic surface on the parabola antenna. A parabola antenna includes a parabolic surface reflector(11) and a radiator(12). The radiator is arranged at a wave focusing position in front of the parabolic surface reflector. At least one through-hole is formed on a solid parabolic surface(13) of the reflector. A shielding wall(20) is extended to a front portion of the parabola antenna outside the parabolic surface. An edge portion of the reflector is curled up. The parabola antenna includes a bracket(18) supported by a structure. The bracket includes a reinforcement blade(19) which is contacted with the edge portion of the reflector.
