Mating the Vertical Sections to the Tilt Base

 

 

 

CAUTION:   Attempting final assembly without proper precaution can be dangerous. 

 

You should have someone help you steady the vertical antenna sections during 

mating with the base section. 

 

 

Note:   A  pair  of  sawhorses  or  ladders  should  be  used  to  support  the  vertical  sections 

during assembly with the Tilt Base and whenever the vertical is tilted down. Do not 
allow the tilt-base to support the entire weight of the vertical when horizontal. 

 

When the upper element sections are assembled together install the black vinyl cap in place at the 
top of the smallest element section.  

 

 
Mate the vertical sections to the base tube section by sliding the bottom 1-7/8" OD element of the 
vertical into the 2" OD base section element (which was previously mounted to the insulated 
channel) to the 6" mark you previously made. See 

Figure 11

. The two sections will have a snug fit, 

so use a small amount of Penetrox A on the bottom section to make the fit easier. Slide the band 
clamp down between the slits, and tighten.  
 
 

Raising the Vertical

 

 

 

DANGER

: Make sure you have not inadvertently located the 

antenna underneath power lines.   

Residential power lines are often less than 40' high. 

Contact With Any Power or Utility Lines Can Be Lethal ! 

 

 
The tilt-base certainly makes it easier however, this antenna can be challenging to put up the first 
time or with gusty winds. If you have properly laid out your optional guy system in advance, it will 
help keep the vertical stable as you raise it – and stop you from 
going beyond vertical at the apex of the lift. 
 
Make sure the optional guy ropes are in the clear before you 
begin.  
 
While raising the antenna, keep a constant pulling pressure away 
from the Tilt Base. This will ensure that the pivot point bolt will 
not jump out of the pivot slot and cause the tilt mechanism to 
bind up and bend the bolts. 
 
Starting from the top of the antenna, walk it up slowly using an overhead hand-over-hand motion, 
maintaining a slow and steady pace.
