Using 

Figure A-1

, place the element clamps over the appropriate tubing.  

 

When tightening the element clamps, install them approximately 1/4" to 1/2" below the end of 
the slit tube with the worm tightening drive as shown in 

Figure A-5, 

located between two of 

the four slits. 
 
 
 
 
 
 
 
  

Figure A-5 

 
 
 
NOTE: At three locations, there are three element clamps installed. Two same sized clamps are 

on the element with the slit, the third clamp is located right next to the larger element. See 

Figure A-6

.  

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Figure A-6

 

 
To avoid damage to the element clamps, do not over-tighten them. 
 
When the antenna elements are completely assembled and mated to the base section, the 
overall length measured from the top of the antenna to the feedpoint on the base section 
should be 847” (70 Feet, 7 inches) 

prior to tuning
