STEP 2:

 

 Bring the completed reflector assembly 
 to the pedestal and locate it about 1-1/2 
 to 2 feet away from the mast.

 

Make sure  

that the elevation tab on the canister is    
pointing towards the mast. Use the 
 reflector carton (or similar object) as a  
 rest for under the edge of the reflector. 
 Orient the reflector so that the cross-       
tube  of the center hub is perpendicular   
to mast.
