Well, I measured my 9500ci's remote radar antenna and put it in CAD. Then I created a 2D PDF which you can download, print out, and then cut and trim and tape to create a paper 3D 9500ci or STi-R antenna which you can use to check for antenna fit within various installation locations. Dimensions are accurate to 1/16 of an inch. The positions and dimensions of the front of the antenna horns and the STi-R laser sensor field of view are accurately shown to within 1/16 of an inch.
-- Make sure that that your utility which prints PDF documents is set to print 1:1 by unchecking both shrink-to-fit and/or expand-to-fit.
-- The PDF just fits for printers which are capable of printing within 1/4" of the top of the page and 3/8" at the bottom of the page on standard 8-12" x 11" paper.
Here is an example of the printed, cut out, and taped together PDF page which has been turned into a paper 3D representation of the 9500ci or STi-R radar antenna:
Here is a preview of the PDF template:
Finally, here is the PDF document which you can download and print:
