Abstract

An antenna, which may be used for transmission or reception of electromagnetic radiation, comprises a dish (1) shaped reflector for collecting radiation when used as a receiver. The dish (1) is wholly or partially transparent to visible light. Because the dish (1) is transparent it may be mounted on a house (2) without obstructing a view of or from the building. The dish (1) comprises a gauze (6) which is reflective to a particular band of micro-wave radiation carrying a video signal. The gauze (6) may be sandwiched between two plastics laminae (50 and 51). Alternatively the dish (1) may have a permanent substance (52) printed or coated on its surface. This substance would be transparent to visible light but reflective to the particular band of electromagnetic radiation carrying a video signal. In an alternative embodiment the dish (1) is supported on a building with a transparent support (100). <IMAGE>
