Bracket Drawing

ALERT! This drawing needs a few revisions:
  • The diameter for the bolt holes needs to be specified (7 or 8 mm?).
  • The second set of zip tie holes close to the antenna mount on the long version need to move further in or be eliminated entirely.
  • The zip tie holes need to be 2mm larger in diameter to accommodate powder coating.
