THIS PROGRAM IS BASED ON A THEORETICAL MODEL OF A YAGI ANTENNA, MANY ASSUMPTIONS AND SIMPLIFICATIONS HAVE BEEN MADE. THE RESULTS OBTAINED WITH THIS PROGRAM MUST THEREFORE BE TAKEN WITH SOME CAUTION. IN OTHER WORDS IF YOU BUILD AN ANTENNA THAT HAS BEEN DESIGNED WITH YAGICAD DON'T EXPECT TO GET IT WORKING EXACTLY AS CALCULATED WITHOUT AT LEAST SOME EXPERIMENTAL ITERATIONS. IE. YAGICAD IS NO SUBSTITUTE FOR A VSWR METER ETC., AND AT LEAST SOME TRIAL AND ERROR. ANYONE WHO DOESN'T AT LEAST USE A VARIABLE CAPACITOR OR HAVE SOME MEANS OF VARYING A GAMMA ARM LENGTH IS EXPECTING TOO MUCH FROM THIS OR ANY OTHER ANTENNA PROGRAM. 

DISCLAIMER

In no event or way will the Author be responsible or liable for any damages, including any lost profits, lost savings or other incidental or consequential damages arising out of the use of or inability to use these programs, even if the Author has been advised of the possibility of such damages, or for any claim by any other party. 

YAGICAD 6.0 is FREE
                                                        
Unlike the very early versions of YAGICAD which were released under a shareware banner(not that I ever made any money out of them) version 5.0 and on are presented free. I offer it to the worldwide community of antenna experimenters in part repayment for the advice and invaluable input I have received from them over the years. It is my hope that it will be useful to them and also help to introduce new people (and especially radio amateurs) to the joys of antenna experimentation. I do however retain the copyright, and if someone wanted to include this program in some book or software collection I would appreciate being at least asked first. I can be contacted at the addresses below. Similarly if you have any comments or feedback please feel free to email me. I can't guarantee a speedy reply but I probably will get there eventually
