4. GENERAL ASSEMBLY OF HALF ELEMENT SECTIONS 

We recommend assembling the half element sections on 
a clean, flat surface.  There is an assembly drawing for 
each of the six elements with both the right and left 
halves shown on each page.  We also recommend 
briefing yourself with the general directions before 
skipping to the assembly drawings. 

The general assembly procedure for a half element section 
begins with laying each capacitor assembly on a level 
surface, with the 10m capacitor tube on the left hand side.  
Locate the two swaged 3/4” dia. tubes and the 5/8 x 6” 
fiberglass rod. 

NOTE: BE SURE TO USE THE CORRECT 

LENGTH 3/4” SECTIONS MATCHING UP WITH THE 10M 
CAPACITOR LENGTH.

 Insert the fiberglass rod into the 

LIGHTLY swaged end side of the longer 3/4” section.  Align 
the two holes and secure loosely with a single 8-32 x 1” screw 
and lock nut in the outer hole as shown in Figure 4.  Next 

slide the other end of the fiberglass rod into the center hole of the 10M shorting bar connected to the 10m 
capacitor.  Slide the larger diameter swage of the shorter 3/4” X 12” tubing through the hole of the shorting bar 
connected to the 15m capacitor tube.  Secure with a single 8-32 x 1” screw and locknut, again through the 

OUTER HOLE 

in the figure.  Now insert the inner two 8-32 x 1” screws and locknuts, and tighten LIGHTLY. 

NOTE: IF YOU OVER TIGHTEN, YOU MAY NOT BE ABLE TO MOVE THE SHORTING BARS TO FINAL 
POSITION.    Slide the two shorting bars right up against the two inner locknuts as shown.  Now tighten all four 
inner and outer screws and locknuts.  Position the capacitor tube assembly so that the gap rests in between the 
two shorting bars and MAKE SURE THE MARKS YOU MADE ON THE 3/8” TUBE ARE 

UP

.  Tighten all of the 8-

32 hardware installed to this point. 
Locate the appropriate 1/2” element tip section and insert the end with 2 holes into the 3/4 x 12” swaged end. 
Secure the 1/2” tip with two 8-32 x 1” screws and locknuts. With a tape measure hooked to the inner edge of the 
15m capacitor tube shorting bar, make a mark on the 3/8” tube at the dimension called out for the 15m shorting 
bar.  Slide the 15m shorting bar onto the 3/8 and 1/2“ tube and set the inner edge of the bar to the mark. Install 

two 8-32 x 1” screws, add locknuts, align with the other bars and tighten.   
Locate the 10m shorting bar and the shorter 3/8” tube.  Using a tape measure connected to the inner edge of the 
10m capacitor tube shorting bar, mark the dimension called out for the 10m shorting bar.  Slide on the 10m 
shorting bar, set the inner edge to the mark and tighten the top 8-32 screw.  Now insert the shorter 3/8” tube 
through the other hole on the 10m shorting bar and into the free hole on the 10m capacitor tube shorting bar.  
Allow the tube to extend 1” past the shorting bar connected to the 10m capacitor and tighten the 8-32 hardware 
on both of the shorting bars.   
 
 
Using the general directions above and the six TIP DIMENSION / ASSEMBLY drawings, proceed in fabricating 
the 12 half element sections.  After double checking your dimensions and making sure that your elements are 
labeled correctly proceed to the next step.
