Abstract :
Use of ultrahigh frequencies for educational broadcasting has been thought to offer attractive possibilities because of the supposedly almost unlimited number of channels; however, the demands of other radio services, particularly television, may be expected to congest this newly opened region. Ultrahigh-frequency waves behave somewhat like light waves, and give reliable and steady communication over short distances. The 6-megacycle band width required for television can be accommodated only in this region, but short range precludes, for the present, coverage of rural areas with these frequencies.
