VHF/UHF Ground-Air-Ground Communications Siting Criteria.

摘要

The report presents results of tests accomplished at the National Aviation Facilities Experimental Center (NAFEC) and selected Federal Aviation Administration (FAA) field facilities to determine radio frequency communication problems and equipment performance under Remote Transmitter Receiver (RTR) and Remote Center Air-Ground(RCAG) configuration. Performance characteristics of antennas,transmitters,receivers,transmission lines,and ancillary equipment were investigated to determine the parameters that affect mutual interference when these equipments are combined in FAA system configurations. The results of the investigation were limited to equipment in current use at field sites and equipment recently developed. Data are incorporated in Appendix A of the report for use as a field manual. The field manual was prepared to provide reference and guidance to installation and maintenance personnel on interference aspects in correcting similar problems at existing sites and the application of these principles in establishing new sites.
