MIL-HDBK-420

Abstract

This handbook describes responsibilities and suggests procedures for conducting site surveys. It is not intended to serve as a stand-alone comprehensive reference for generating reports. Rather, it is to be used in conjunction with existing site-specific handbooks and other applicable documents to identify requirements needed to support the acquisition, establishment, or upgrading of telecommunications sites. <br>This handbook contains sections that give the responsibilities, operational duties, and data collection requirements for both the presurvey and the on-site survey teams. Section <a>4</a> (General Requirements) contains site installation categories, survey team composition, responsibilities, team operation, and report generation guidelines. Section <a>5</a> (Detailed Requirements) identifies data requirements that are: (1) common to all telecommunications facilities and (2) related to specific types of telecommunications sites. Appendixes contain detailed information, sample calculations, and data collection worksheets. The data collection worksheets, as modified by the survey team, form the nucleus of the data collection workbook used by both the presurvey and the on-site survey teams. Since information requirements and report formats used by military departments can differ significantly, this handbook contains no recommended format. The site survey team should contact the department with approval authority for guidance on report format and content. <br>This handbook is intended as an aid in the performance of telecommunications site surveys. It is applicable to the establishment or expansion of line-of-site stations, tropospheric scatter stations, satellite communications earth terminals, high frequency transmitter and receiver stations, interconnect communications facilities, submarine cable terminals, fiber optic communications, switching centers, and local area networks. <br>Telecommunications equipment normally involves high voltages and, in some installations, high energy radiation fields. Systems and subsystems discussed in this handbook shall comply with the safety requirements established in MIL-STD-882, the safety portion of MIL-STD-1472, and OSHA 1910.
