Abstract:

A Traffic Control and Landing Systems TRACALS Communications Station Evaluation was performed at Ellsworth AFB, South Dakota 2184 Comm Sq from 27 March thru 4 April 1978. The purpose of the evaluation was to define the capabilities and limitations of the communications system servicing the radar approach control RAPCON and control tower. Included in this report are the results and analysis of equipment checks, system line-level diagrams, line-of-sight coverage data, analysis of airborne measurements of signal strength, and plots of UHF radiation patterns. Other items which are discussed in this report and are common problems with most other systems, include system alignment procedures, and antenna maintenance problems. The data and diagrams in this report can be used as a guide for anticipated performance of the communications system at Ellsworth AFB until there is a deletion, addition, relocation of equipment, or a change in horizon profile which would effect the system. This report will remain valid after relocation of the transmitter site. Author
