Technical Documents

We have published 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. You can find the most relevant documents here.

 

Our DF software literature consists of a Product Datasheet (Brochure) and the HuntMaster's Express Operator's Manual for customer reference. A HuntMaster Downloadable Demo Release is also available in the public Download area of this site. HuntMaster's Networking capabilities are not explicitly showed in this documents due to security reasons. Please get in contact with us if you need further information on HuntNET technology.

We are constantly adding new technical content. Nevertheless, if you don't have the answer to the question you looking for readily available online, please feel free to contact us.

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:

 

WN-001- Q&A:  A User's Guide To Radio Direction Finding Basics

WN-002- Basics of the Watson-Watt Radio Direction Finding Technique

WN-003- Q&A:  A User's Guide To Radio Direction Finding Receivers And Bearing Processors

WN-004- A Comparison of the Watson-Watt and Pseudo-Doppler DF Techniques

WN-005- Q&A:  A User's Guide To Radio Direction Finding System Bearing Accuracy

WN-006- Q&A:  A User's Guide To Radio Direction Finding System Sensitivity

WN-007- Q&A:  A User's Guide To Using Loop Versus Adcock Radio Direction Finding Antennas

WN-008- Q&A:  A User's Guide To Radio Direction Finding Antenna Selection

WN-009- Q&A:  Selecting the Right DF Receiver/Processor 

 

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. A 'must read' for the serious DF system customer. 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.
 

AN-002- A Comparison Of Loop And Adcock Antennas For Single-Frequency Fixed-Site Radio Direction Finding Applications. 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.
 

AN-003- Measuring Bearing Accuracy Of Mobile Adcock Radio Direction Finding Antennas. 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.
 

AN-004- Measuring Sensitivity Of Mobile Adcock Radio Direction Finding Antennas. 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.
 

AN-005- An Introduction To Dipole Adcock Fixed-Site DF Antennas. 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.
