The invention provides a multilayer coating film-forming method that allows formation of a multilayer coating film with excellent smoothness, sharpness and water resistance, and which avoids or minimizes pinhole popping. This invention was made in view of such a problem, and aims at offering a radome with little cover of electromagnetic waves, absorption of electromagnetic waves, and dispersion of electromagnetic waves by the member of a radome. When the supporting bracket is applied to an object thereon, the back plate is rotated up relative to the fixed member, the moveable member is rotated up relative to the fixed member, the locking unit is inserted into a slot of the back plate, and the object is supported on the back plate in a tilted manner with a bottom of the object sandwiched between the stopping tab and the back plate. The two swingers of each pivot-cross are coupled with the respective adjacent shaft-ends rotating at same direction when the adjacent shafts turn about the swinger-pivots and, at two opposite directions when the adjacent shafts turn about the cross-pivots, located perpendicularly to the swinger-pivots. The compounds can be used for the treatment of infertility. A channel quality measuring device included in the base station monitors the channel quality of the uplink common control channel and provides a quality margin for the communication signal.
