Plane reflector:
  Is square.
  Is 11 and 11/16 inchs on each side.

Waveguide (can):
  Is round.
  Is 3 and 1/2 inchs in diameter.
  Is 6 and 3/16 inchs long.
  The back end of the waveguide is located 1 and 7/16 inchs
  above the plane reflector.


Probe:
  Is parallel to the bottom of the can.
  Is vertical with respect to earth.
  Is 2 and 1/16" from the back of the can.
  Is 1 and 7/32" long including the brass part of the N-Type
  connector.


Notes:

Use a balanced feed.

When using wire mesh at these frequencies use mesh that is a minimum
of 1/2 inch mesh.  I strongly recommend 1/4 or 1/8 inch mesh.

You can use a 3.5 inch PVC pipe joiner to construct the offset spacer
you will need to mount the waveguide the correct distance from the
plane reflector.
