<P>PROBLEM TO BE SOLVED: To provide an antenna capable of receiving vertically polarized waves and horizontally polarized waves with successful characteristics. Ž<P>SOLUTION: A first radiator 31 is attachably/detachably attached to a holding part 21 for the first radiator, and held at either of a vertically polarized wave position suitable for reception of the vertically polarized waves or a horizontally polarized wave position suitable for reception of the horiontally polarized waves, and a second radiator 32 is attachably/detachably attached to a holding part 22 for the second radiator, and held at either of the vertically polarized wave position suitable for reception of the vertically polarized waves or the horizontally polarized wave position suitable for reception of the horizontally polarized waves. A holding part 41 for a first waveguide is attachably/detachably attached to the holding part 21 for the first radiator, and held at either of the vertically polarized wave position suitable for reception of the vertically polarized waves or the horizontal polarized wave position suitable of reception of the horizontally polarized waves. A holding part 42 for a second waveguide is attachably/detachably attached to the holding part 22 for the second radiator, and held at either of the vertically polarized wave position suitable for reception of the vertically polarized waves or the horizontally polarized wave position suitable for reception of the horizontally polarized waves.
