The bowl-shaped housing is mfd. from reinforced, hardenable plastics and/or reinforced concrete, and along its length has relatively thin material thickness. The greatest cross-sectional dimension for the antenna unit (2,3) is at least 70 per cent of the corresponding greatest internal measurement of the housing (1). - The housing either encloses the antenna unit and/or casing in a self-supporting manner, or forms with them a suitably rigid unit. It is formed with a part (1b) through which passes the radiation with which the antenna unit works, and with which part the reflective surface on the antenna unit is adjustable. The housing forms a frame together with a bearing part (7), frame leg, or corresponding support component. The frame is used to adjust the reflecting surface in the required direction.
