6.  Install the Black Vinyl Cap on the top

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 to the studded band clamp. The shield 
from your coaxial feedline must connect to 
the base plate where you connect your radial 
wires.
