Guying a Vertical Antenna System 

 
Guying of vertical antennas is always recommended for stability. However, if your area encounters 
severe wind velocities or icing conditions, simple guying will reduce the possibility of failure. 
Using the 

DXE-GUY

 kits, you can install four guy ropes starting approximately 1/2 the way up the 

vertical antenna system to ground level. Guying should be tightened just enough to permit the 
antenna to swing a few inches. The ends of the ropes are tied to the earth anchors that are screwed 
into the ground at about the same angle as the ropes will be.  When using the Tilt Base, position the 
guy wires as shown below.  This will make it easy to raise or lower the antenna and only one guy 
line needs to be loosened. The other guy lines will help guide the antenna on the way up. Depending 
on your antenna system, additional guys at points higher on the antenna may be required.

25 feet from the

Note:

 Depending on wind and  

          ice conditions, additional  
          guying may be necessary.
