some of my new desings might use a coax chamber and a non coax chamber. ggdt does not allow for this dual chamber configuration. so i made this simple excel spread sheet to do this for me.
its rele easy to use. just type in all the values that you need in the yellow input section and it does the calculations as soon as you click out of that box.
remember the chambers i call "coax" and "normal" are two completly seperate chambers! if you are making a plain coax then just use the coax chamber input and leave the other blank.
if you mouse over each label there is a description that should help. also on sheet two of it there are common dementions for pvc, copper, and iron pipe.
and problems or comments just post em!
