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.

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.
