    A UHF satellite installation is described. Average field strength improvements of nearly 23 db were obtained in a deep shadow area at Waterbury, Connecticut. 80 db of straight RF amplification was used in conjunction with high gain receiving and transmitting antennas on a frequency of 700 Mc/s.

    A transistor video amplifier which has sufficient output signal, swing, and bandwidth to drive a standard picture tube is described. The amplifier consists of three junction transistors in the following configurations (starting at the input end): grounded-collector, grounded-emitter, and common-base. A resistive feedback path is provided from the output of the grounded-emitter stage to the amplifi... View full abstract»

    The side-fire helical antenna, successfully used for UHF and VHF high channel television transmission, has now been adapted for low channel VHF service. Investigation of properties of a helical radiator wound around a polygonal supporting structure has made possible the required increased bandwidth and provided directional patterns for special TV coverage applications. Through scale model work, a ... View full abstract»

    With a sectionalized tower high angle radiation can be minimized to give better ground wave performance than is possible with a simple vertical radiator. A study of theoretical conditions in conjunction with physical limitations reveals that it is necessary to maximize the current distribution on any given tower construction to obtain the maximum ground plane field intensity. Several sectionalized... View full abstract»

    Modern professional magnetic tape recorders and reproducers are capable of performing many of the menial chores of radio and TV broadcasting. Pre-recorded announcements accompanied by subaudible tones can control the operation of several tape program reproducers or juke box type automatic record players. Simple systems are available which alternately switch from an announce machine to a program ma... View full abstract»

    The Postmaster-General's Department has developed a range of aerial systems suitable for National Broadcasting Service transmitting stations of powers from 200 watts to 50 kilowatts in the frequency range 540-1600 kc/s. The aerial systems fall into two classes: ``high'' aerials having special anti-fading properties, usually near half-a-wavelength in height, and ``low'' aerials less than a quarter-...

    The alternatives are described for achieving one megawatt Effective Radiated Power in the UHF-TV band. The new 0-E 45 KW and 23 KW transmitters are described. The different high power antenna approaches are discussed. Steps towards converting existing 1 KW and 0-E 12 KW stations are explained in detail. View full abstract»
