§ 79. Mr. Onslowasked the Secretary of State for Education and Science what research has been conducted by the Radio Research Centre, Slough, into the propagational characteristics of the atmosphere in the first few hundred feet above the earth's surface at a frequency of 7,000 MHz; and when this research was published.
§ Miss BaconNo investigations have been carried out at the specific frequency of 7,000 MHz✶, but the behaviour of waves at this frequency can be in- 172W ferred from experiments which have been conducted at both lower and higher frequencies.
Results of these experiments have been published in the Radio and Space Research Station Annual Reports between 1956 and 1964 and in various scientific and technical journals.
