6.  Install the Black Vinyl Cap on the top element. 
 
7.  The two stainless steel V-Bolt Clamps are used to 

secure the mounting plate to the customer supplied 
mounting pipe described earlier in this manual. When 
the antenna is installed on the mounting pipe, tighten 
the V-Bolts evenly so the length of the exposed 
threads is approximately equal. Any V-Bolt should be 
tightened evenly from side-to-side with an equal 
amount of thread above each nut. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
8.  Connect the center conductor of your coaxial feedline

coaxial feedline must connect to the base plate where 
you connect your radial wires.
