Here is a picture showing two elements, the 
Special IEC, and the three Guy Lines 
assembled together.  This connection point 
for the Guy Lines is usually about head-
high, or just above, in the element stack.  
                                                                   

             

At the other end of the Guy Line, the line is 
threaded through two of the holes in the 
Guy Line Slider, and is tied to the third 
hole.  A bowline knot is recommended 
here.   

 

For each Guy Line, the loop between the 
tied end of the guy line and the middle hole 
goes over a Guy Stake, which is spaced 
about 10’ away from the antenna base.  
Then the three sliders are adjusted to 
equally tighten the Guy Lines, while 
checking that the antenna is straight. 

 

The slider moves very easily toward the 
antenna, tensioning the guy line.  To loosen 
the slider, grasp and hold the guy line on 
the antenna side of the slider, turn the slider 
slightly with your other hand, and slide it toward the stake.   

 

The HFp Wrench 

The HFp wrench is designed to loosen 
a stuck IEC (Inter-Element-Connector) 
from the end of an element - a 
common problem when the elements 
are tightened securely.  

 The wrench is made of hard 
aluminum, and may be held in the 
hand, or may be attached to the base 
plate of the Vertical.  It weighs about 
1.2 ounces. 

The Vertical base plate application of 
the wrench makes it extremely 
convenient to loosen a stuck IEC.  
Removing a stuck IEC is now a one-
hand operation! 

To loosen a stuck IEC, simply insert the IEC stud into the IEC hole in the base plate, turning the 
element slightly to align the nut flats with the wrench slot.  Then twist the element (to the left!) 
to loosen the IEC.
