Acknowledging the presence and potential of radiation hazards, the planning and design of a modern nuclear generating plant employs techniques to accommodate and control such radiation. Some of the techniques employed to provide this control are: the extensive use of lead shielding, extra thick steel reinforced concrete walls, and corridor design utilizing short hallways with numerous zigzags, all of which also not being conducive to the propagation of radio-frequency energy. The purpose of this paper is to describe a highly successful and reliable method of providing UHF radio cummunications throughout several radio-frequency isolated buildings. The system to be described will rely on slotted line transmission lines, multiple antennas and full duplex in-line RF power amplifiers. Engineering design considerations discussed will include: theory of operation, intermodulation product concerns, and the selection of commercially available equipment for ease of installation and maintenance.

A newly designed 400MHz band antenna diplexer has been developed for land mobile communication system. The diplexer has been miniaturized to the volume of about 400cc by using dielectric resonators and the design technic of elliptic function type band elimination filter. The diplexer has high performance for insertion loss, isolation, transmitting power capacity and temperature stability.

A "panel" antenna can be defined as a directional antenna composed of a dipole, or combination of dipoles, in front of a flat reflector screen. The flat screen differentiates it from corner reflector or parabolic reflector types of antennas. This paper deals with a special version of panel antennas employing two dipoles side-by-side in front of a flat screen, providing special properties, The four properties discussed are principally derived from the extremely broad bandwidth provided by the two dipole configuration.

The simultaneous transmission of the same audio from several conventional FM base stations over a wide area has been known to provide operational advantages and performance improvement in many cases. The technique has seen limited application, however, due to the requirement of stable microwave audio links to each of the base stations. A system that circumvents this requirement is described. Automatic equalization periodically compensates for changes in amplitude response and phase delay, allowing operation over conventional private lines leased from the telephone company. The system uses these same facilities to synchronize continuous tone-coded subaudible squelch (CTCSS). The simulcast electronics interfaces to the dispatch system through a microcomputer that also controls the signalling subsystems, providing the dispatcher with the ideally simple "push-to-talk" operation.

The continuing quest for improved service and operational efficiency in rail transit systems has led to the use of newer designs in signalling and propulsion subsystems. Although these new designs have produced resource savings in these energy and cost-conscious times, they have the potential for generating electro-magnetic interference problems -- problems that also must be dealt with in a cost-effective manner.

Guided radio communications using signal boosters and distributed antenna systems is a developing art that was not anticipated in the present FCC Rules and Regulations. This has resulted in confusion in the radio communications industry and numerous inquiries to the FCC staff regarding type acceptance of signal boosters and licensing of distributed antenna systems. This paper outlines the procedures for preparing fsapplications for FCC type acceptance of signal boosters, the pertinent FCC Rules and Standards, and it explains matters relating to licensing distributed antenna systems.
