Telecommunication apparatus is provided that is formed from or includes fibre glass or a glass reinforced plastic material, with one or more electrical conductive surfaces provided on or associated with said fibre glass or glass reinforced plastic material. Aspects of the invention include the apparatus in the form of a whole or part of radio frequency apparatus; or a radio frequency filter housing body or radio head, with or without a housing lid. The fibre glass or glass reinforced plastic material has the advantages of being inexpensive, lightweight, non-brittle, thermally stable, easily adapted to moulding processes, strong and robust and the electrical conductive surfaces provided thereon or associated therewith provide the apparatus with the necessary electrical conductive and/or RF properties. |
