Web Notes are short papers covering topics of general interest to DF users. These papers are written in an easy-to-read format for users more focused on the practical (rather than theoretical) aspects of radio direction finding technology.<\/p>\n<\/div>
Application Notes are published to help illuminate various aspects of radio direction finding technology. These papers are more formal and detailed, covering radio direction finding topics in greater depth than the shorter and less technical Web Notes listed above. These Application Notes (listed below with a brief synopsis) are published in Adobe Acrobat PDF format for convenient download.<\/p>\n<\/div>
This paper helps the prospective buyer untangle the mysteries of the DF equipment selection process so that informed and cost-effective purchasing decisions can be made. Topics include budgetary considerations, fundamental DF system configurations, mobile versus fixed-site DF systems, attributes of professional-quality DF systems, plus evaluating and dealing with the DF equipment vendor.<\/p>\n<\/div><\/li>
Discusses the relative merits of Adcock and loop DF Antennas for fixed-site radio direction finding applications using a 30 MHz installation as an example.\u00a0 Illustrates in detail the inferiority of both ferrite and brass loops with respect to Adcocks in terms of both bearing accuracy and sensitivity.<\/p>\n<\/div><\/li>
Provides an in-depth discussion of the concepts and principles underlying radio direction finding system bearing accuracy measurement.\u00a0 Also discusses techniques and procedures that technical users can refer to as guides for conducting their own bearing accuracy tests.\u00a0 Offers important insights as to how to interpret manufacturers’ bearing accuracy specifications, as well as how to avoid “specsmanship” traps.<\/p>\n<\/div><\/li>
Provides an in-depth discussion of the concepts and principles underlying radio direction finding system sensitivity measurement.\u00a0 Includes detailed information that technical users can refer to for constructing their own reference antennas and test ranges.\u00a0 Offers important insights as to how to interpret manufacturers’ radio direction finding sensitivity specifications, as well as how to avoid “specsmanship” traps.<\/p>\n<\/div><\/li>
