Abstract (en)
A dish aerial, for example for receiving satellite broadcast signals, includes a primary dish (10) and a ring of forwardly extending legs (11) and a cylindrical housing (17) which are integrally moulded from a thermoplastics structural foam material. A member (30) defining a secondary reflecting surface and also moulded from such material or formed from metal is located with the forward ends of the struts (11) to be in the correct relationship to the surface of the dish (10) to produce a focus for incoming parallel radiation at (15) on the principal axis of the aerial. That point (15) is within a space (16) within the tube (17) and sealed from the weather.
