Airborne UHF Communications Equipment

After more than two years' experience, it has been determined that airborne UHF communications is satisfactory. Many unforeseen types of interference have been found, some of them serious. Antenna patterns on aircraft are not ideal, but are usable. The newest subminiature airborne transceiver has undergone unique operational engineering tests. Results show that its design is highly desirable from the aspects of performance, installation and maintenance. Until the ultimate design of an equipment requiring no maintenance, industry should improve quality of components to increase reliability and reduce repairs.
