This program is modeled after the article published in Ham Radio, December 1988, by K5IU.
That article presents a good background for those of us who enjoy building antennas. I believe his points on structural reinforcement to ensure lighter elements are well taken. I encourage you to follow those ideas while running STRESS.EXE.
This program was written and compiled with Borland's Turbo Pascal 4.0. The program is almost entirely menu or instruction prompted. It allows fixed wind velocities corresponding to the latest EIA standards. Gusts may also be considered. The program assumes all construction is identical Aluminum alloy.
When element size is inputed, please note the following. Element size is entered for half elements, that is tip progressing inwards towards the boom. The number of segments and their length are entered as integer values. Should one wish to use tubing diameter or wall thickness not listed in the tabular input by selecting choice "O", please use real number inputs (eg. 4.0, 0.123, etc.). The program will consider only 8 different segments per element.
The program will not store output data but the PrtSc command can be used to provide hard data output while calculating antenna designs. Be sure all letter inputs are in capital form.
This program, used in conjunction with antenna design or analysis programs like MININEC or YAGI DESIGN, will afford one the ability to design a superlative electrical and mechanical antenna.
