Device and housing for radio transmission reception |
摘要 |
A housing for a radio transmission receiver for very high frequencies, specifically for the 30 GHz range. The housing contains alignable antennas for dual directions. The housing is water-tight and contains a complete transmitter-receiver so that only modulation signals and a feed voltage are supplied from the outside. A compact and electrically efficient internal format, particularly of the radio frequency unit, is a principle feature of the invention.
