Scroll to the end of the file to see the hairpin dimensions. EXE - the software - plus a desktop icon file. The compressed file includes AAT. The new data site is called the "National Map". This updated version 1. However, the "Save radials" option, although present, may be greyed out and cannot be selected. Thanks, Doc N7DR. That should enable the "save radials" option during the viewshed procedure. During the original CD installation process you were asked to specify the region where you live so that appropriate statistical elevation-angle files could be installed along with HFTA.
You may wish to replace the files currently in this directory with these to achieve greater accuracy. The statistical elevation angles are computed for the full year solar cycle from transmitting sites indicated by the filename. Graphing Spreadsheets by Rudy Severns, N6LF - In the process of generating the graphs for several figures in Chapter 3, typical values were chosen for such variables as vertical height, frequency of operation, power level, ground characteristics, etc.
In these spreadsheets, you can choose your own values for those variables and the graphs will change accordingly. The compressed ZIP file includes two spreadsheets and an instruction document.
Seawater Grounds by Rudy Severns, N6LF - In this article, Rudy addresses the situation of installing a vertical antenna on a dock, pier, or beach and the effectiveness of using salt water as a ground. Dimensions for the monoband Yagi hairpin matching wires are given in the YW file for that antenna. Be sure to download the element detail drawing , as well.
Figure Giving a single equation for parallel-conductor lines with plastic insulation is not practical because of the many variations in dielectric cross-section. For these cases, check with the feed line manufacturer for the correct characteristic impedance. The paper provides general information about communications effectiveness as related to the physical height of antennas. The intended audience is amateur radio operators and the city and town Planning Boards before which a radio amateur must sometimes appear to obtain building permits for radio towers and antennas.

I simplified the feed connection to make it easier to build. Instead of the original transformer feed, the coaxial feed line cable is now connected directly to the driven element. An impedance match is achieved by connecting a 0. Ten ferrite beads using 73 ferrite material 0. Given that the 30 meter band is fairly narrow, it is important to follow the element taper schedule closely. For example, in a recent build, the initial minimum SWR point was at To re-center the minimum SWR point at The shift in frequency can be simulated in the model, as well: a 1.
