RADIO DIRECTION FINDING APPLICATIONS LITERATURE & SOFTWARE
RDF Products publishes a variety of applications literature both to aid users in their selection of new radio direction finding products as well as to help users more effectively deploy and operate their existing radio direction finding equipment:
Web Notes: 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. These Web Notes (listed below) are published in Adobe Acrobat PDF format for convenient download:

Application Notes: RDF Products also publishes Application Notes 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:
AN-001 -
A User's Guide: How To Shop For A Radio Direction Finding System
(March 2000). A "must
read" for the serious DF system user.
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. (B03-1,388k)
AN-002
- A Comparison Of Loop And Adcock
Antennas For Single-Frequency Fixed-Site Radio Direction Finding Applications (June
1994). 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.
Illustrates in detail the inferiority of both ferrite and brass loops with respect to
Adcocks in terms of both bearing accuracy and sensitivity. (C01-459k)
AN-003
- Measuring Bearing Accuracy Of Mobile
Adcock Radio Direction Finding Antennas (October 1994). Provides an
in-depth discussion of the concepts and principles underlying radio direction finding
system bearing accuracy measurement. Also discusses techniques and procedures that
technical users can refer to as guides for conducting their own bearing accuracy
tests. Offers important insights as to how to interpret manufacturers' bearing
accuracy specifications, as well as how to avoid "specsmanship"
traps. (C01-1,131k)
AN-004
- Measuring Sensitivity Of Mobile Adcock
Radio Direction Finding Antennas (January 1995). Provides an in-depth
discussion of the concepts and principles underlying radio direction finding system
sensitivity measurement. Includes detailed information that technical users can
refer to for constructing their own reference antennas and test ranges. Offers
important insights as to how to interpret manufacturers' radio direction finding
sensitivity specifications, as well as how to avoid "specsmanship"
traps. (C01-1,588k)
AN-005
- An Introduction To Dipole Adcock Fixed-Site DF Antennas (December
1999). Provides an in-depth discussion of the philosophy underlying dipole
Adcock DF antennas for mast-mounted fixed-site applications. Explains the
reasons for the vast superiority of dipole Adcocks over elevated ground-plane
monopole Adcocks. Discusses the serious problems associated with the presence of
the support mast for dipole Adcocks and how RDF Products has overcome them.
(B05-1,064k)
AN-006
- An Introduction To 8-Element Adcock DF Antennas (May 2016). Provides an in-depth discussion of the
history, technology, and application of 8-element Adcock DF antennas.
Explains the underlying reasons for their ability to cover much wider frequency
ranges than 4-element Adcocks, but also their limitations. Discusses their
favorable characteristics for HFDF applications. (A01-928k)
