Brief Description:Fabricated the VOR antenna doubler, match drilled, dimpled, and prepared for final install.


VOR antenna doubler made.

Bryan made his first venture to take a look and contribute to the project.  We took the antenna out of the box, marked the spot on the VS-1006 top rib where I wanted to place it, cut a doubler plate, and began drilling, dimpling, deburring, and fitting.  The antenna elements screw into the vor “puck” and have allen head set screws that need to be set once the elements are in place.  These screws are on the same elevation and plane as the elements and approx 90 degrees perpendicular to the axis of the elements.  The only holes left to drill are (2) into the VS skin to match the holes in the sides of the top rib and the holes into the VS-1013 and VS-1004 inspar ribs for the stand offs to hold the conduit.  I have also yet to determine how the conduit will terminate on EITHER end and which holes in the inspar ribs it will travel into.  I would also like to add another run of conduit in the nose ribs for a VS camera mounted in the fiberglass tip.

VOR Antenna Remove/Replace goes like this:

  1. Remove safety wire and (4) fillister slotted screws.
  2. Tilt puck’s leading edge side upward and slide to one side to gain access for ball ended allen wrench to loosen one set screw on that side then unscrew element.
  3. Slide puck to other side, loosen set screw, and remove element.
  4. Gently lift up puck, place zip tie with zip tie-tail left on just below BNC connector to ensure that when BNC connector is removed the loose antenna cable does not fall into conduit.

Installation is the exact opposite with the exception that you would add new grommets and lubrication on them prior to inserting the new elements.
