FYI - because there is always some inadvertent scaling of images when scanning and reprinting templates, you have to carefully check measurements - and it could depend on your software, and your printer. I've found that when I print the attached document using my pdf reader and my printer, the measurements are slightly off. I had to print at 101% (again, my pdf reader) in order for the distance between the mounting bolts on paper to be 4.75 inches, which is the physical distance between the bolts on the antenna base. Your mileage may vary! If you use the template, print it and confirm the distance between the mounting holes, and adjust the print percentage until you get 4.75 inches. Once that dimension is correct, all other measurements will be spot on.
