A Giant Mast. About £50,000 is shortly to be. spent on the construction of a new station, to be called 6WA, with a mast 700 feet high—2oo feet higher than lYA’s Henderson mast, which has, since its erection, claimed the title of the tallest structure south of the equator. The new station is to be the national broadcasting transmitter which is being erected at Minding, 1-1 miles west of Wagin, in Western Australia. Work on the station is well advanced, and it will transmit on a wave length of 536 metres. The initial power of the station will bo 10 kilowatts in the aerial, but the plans provide for a power of 60 kilowatts. The station is designed to servo an area with a population of 78,000, in which there are only about 4500 listeners at present. It is expected that 6WA will be in operation before tho end of the year, providing day-and-night reception over a 200-inile radius.

licenses in U.S.A. The total number of radio homes in the United States on January 1 last is placed at 21,455,799 in a census report issued by the Columbia Broadcasting System. To this number the report adds 1,800,000 radio-equipped cars and 2,295,770 homes having two or more radio sets, making a grand total of 25,551,569. Cable for Television. Such extremely high signal frequencies are used in television that it is very difficult to avoid serious losses when the signals arc conveyed over land lines between studio and station, although the distance may be short The production recently by the Bell Telephone Laboratories of a cable which, can handle a band of a million cycles is, therefore, of great importance. Not only will it simplify the arrangements of studios aud transmitting stations by allowing them to bo separated from each other, but it will make relay systems possible, an important factor when ultra-short waves are used, with which a multiplicity of stations will apparently be necessary to supply programmes to a large area. The cable will probably also bo of great benefit in carrier wave systems of land-line telephony and telegraphy, as well a* high quality broadcasting.
