What is DA Plotter?
DA Plotter is a custom DOS software product that allows you to "see" your theoretical pattern and see how changes to various parameters affect null, monitoring points, and pattern shape. The program requires VGA graphics and will run under almost any DOS or Windows PC. Download a FULL working four tower DEMO here. Demo.exe
To run the demo under Windows, just double-click the Demo.exe file. This will give you the sample 4 tower pattern, which was originally from WOTT AM, Watertown, New York. You will see the six relative monitoring point values, along with null locations. Use the function keys to change phase and loop values. The relative monitoring points are calculated in real time, and the overall plot is re-drawn when you press "enter" to fix the value change. SCALE allows you to zoom in on the plot. The PLOT function is used when you wish a forced re-draw of the screen.
Prices are quoted per array and pattern, but typical pricing is as follows:
Two Tower - $59.95
Three Tower - $149.99
Four Tower - $199.95
Each additional tower - $55.00
Price includes shipping and handling. New York State residents add sales tax. COD charges extra.
We need a copy of the page in your latest partial or complete proof with a tower placement sketch showing spacing between towers (usually in degrees), tower orientation, pattern parameters and pattern plot. We also need a copy of page one of FCC Section II-A (Engineering Data) or your station license showing current monitoring point radials and values. Please note which tower number is your reference tower if it is not obvious.
