If my math is correct the Focal Distance is between 21 and 22" But I'm not sure if this from the dead center of the dish or even with the outer edge.
If it was dead center then the feedhorn would only be 11" above the dish edge. If it is from equal with the edge of the dish, then it would be 31" from the bottom of the center of the dish. Does anyone know which of these is true? Once I have the correct location for the feedhorn, then it form a triange with a 90 degree right angle and I should be able to find the length of the long side since I would know the 2 other sides. I know there is a formula to do this, but it's been a long time since I was school. AutoCAD would be able to plug these numbers in and find the answer in a second. If you have AutoCAD and can make a sketch, or JPG, SWF , or other type of file, please send it to my primary address [EMAIL PROTECTED] Thanks again Bill --- In [email protected], "ocsrc1" <[EMAIL PROTECTED]> wrote: > > The dish is 59" wide and 10" deep. > > Hope this helps > > Bill > > > > --- In [email protected], "Geraldo Paiva" <loures@> wrote: > > > > Considering the attachments is being stripped away by Yahoo, > please see the two dimensions I need: dia of dish and depth of dish. > > > > > > !------------------ dia of dish ------------------! > > ...................................................... ---- > > .......................!..................... > > ..................!..............
