Mating the Vertical Element 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  antenna  when  in  the horizontal 
position. 

 
Mate the vertical element sections to the base element tube section by sliding the bottom 2-1/8" 
element of the vertical over the 2" base section element tube to the 4” mark you previously made. 
See 

Figures 8 and 10

. The two element sections will have a snug fit, so use a small amount of 

Penetrox A on the bottom element section to make the fit easier. Slide the element clamp down to 
the edge of the bottom section, between the slits, and tighten. For fine tuning, you can adjust this 
bottom section inward or the very top section inward or outward. See the 

Tuning the Vertical

 

section in this manual. 
 
 

Guy Rope and Anchor Installation 

 
Guying is required on this as well as any other vertical antenna, especially in areas where it is windy 
or susceptible to wind gusts. Four screw-in earth anchors and sufficient antenna rope are available 
as model 

DXE-GUY400-KIT

 to allow guying of the antenna at two levels in four directions. Rule-

of-thumb engineering suggests the distance of the anchors from the antenna base should be equal to 
the height of the highest guy level. This provides a 45-degree guy angle.  The guy ropes should be 
fastened just above an element clamp using a non-slip knot as shown in 

Figure 11

 
The set of four earth anchors may be augured into the ground approximately 35 to 50 feet from the 
antenna base to fasten the guy lines. When you install the earth anchors, make sure one of them is 
placed exactly opposite the direction toward which the antenna will tilt over.  The others should 
then be evenly spaced. You may find it easier to first install and raise only the sections of tubing up 
to the lower set of guy ropes.  This will allow you to establish the correct length and tie off the 
ropes.  Then, you can disconnect the guy rope toward the rear and, leaving the others fastened, 
lower the partial sections for final assembly. The remaining ropes will provide stability as the 
antenna assembly is raised. 
 
 

Raising the Vertical

 

 
It is strongly recommended that you have help when you raise this antenna. The Tilt Base certainly 
makes it easier however, this antenna is 68 feet long and can be challenging to put up the first time 
or with gusty winds. If you have properly laid out your guy system in advance, they will help keep 
the vertical stable as you raise it – and stop you from going beyond vertical at the apex of the lift.
