A hinge portion is formed on the base portion. An antenna portion is attached to the hinge portion so as to be pivotable thereabout. The hinge portion includes a hinge base having a first shaft formed on one end thereof, a second shaft formed on the other end thereof, and a first protrusion formed on an outer periphery of the second shaft, and a hinge bush rotatably mounted on the first shaft and engaged with the antenna portion. The antenna portion is formed with a hole surrounding the outer periphery of the second shaft. A projection is formed on an inner periphery of the hole. The first protrusion is brought into contact with the projection when the antenna portion is pivoted so as to define a predetermined angle with respect to the base portion.

A feeding component 40 has a wire (or a feeding line) 42 and an attaching member 43 made of resin. The attaching member 43 provides wire receiving grooves 43a and 43b to receive and support the wire 42. At least one pair of wire holding parts 43d are formed on inner wall defining the wire receiving grooves 43a and 43b. The wire holding parts 43d of each pair are opposite to each other and inclined to narrow a width of the wire receiving groove 43a or 43b with increasing proximity to an upper side of the wire receiving groove 43a or 43b. The wire holding parts 43d hold the wire 42 put into the wire receiving grooves 43a and 43b.

An antenna element including first and second pole antenna elements is inserted in an antenna case. In the antenna case, a main circuit board having first and second surfaces opposite to each other is mounted. Mounted on the first surface of the main circuit board, a first antenna unit receives a first radio wave from a first kind of satellites. Mounted on the first surface of the main circuit board, a second antenna unit receives a second radio wave from a second kind of satellites. On the second surface of the main circuit board, a booster circuit for the first pole antenna element is mounted.

A fixing hole and a locating hole of an automobile's roof are aligned in a predetermined direction while a fixing part and a locator pin of an antenna unit are aligned in a slightly different direction on the condition the antenna unit is oriented in the predetermined direction. The antenna unit is placed on the roof and a male screw is engaged with a female screw fixed to the fixing part to attach a fixing attachment. By tightening the female screw, the roof is held tight between the antenna unit and the fixing attachment and thereby the antenna unit is fixed to the roof. In this case, the antenna unit is oriented in the predetermined direction with a high degree of accuracy due to clearances between the fixing hole and the fixing part and between the locating hole and the locator pin.

A washer 31 is mounted on a cable 20 at one end portion 21 and the washer 31 is staked to a skin of the cable 20. The skin of the cable 20 is coated with polytetrafluoroethylene or PTFE. The washer 31 is made of brass. Subsequently, a bushing member 32 is integrally molded on the washer 31 to the cable 20 by injection molding. The bushing member 32 is made of polyvinyl chloride or PVC. Thereby, a cable bush 30A is mounted on the cable 20 with cable bush 30A securely fixed to the cable 20.

An antenna unit includes a feeding component 40 and a metal plate 50 on which the feeding component 40 is mounted. The feeding component 40 has an attaching member 43 made of resin to support a feeding line against the metal plate. The metal plate 50 has a pair of cut and raised parts 51 at both ends thereof while the attaching member 43 has a pair of locking hooks 432 at both ends thereof. The locking hooks are partly inserted into the cut and raised parts and thereby the feeding component is attached to the metal plate without projecting any parts of the attaching member from a rear surface of the metal plate.
