ARNING! 

 

INSTALLATION OF ANY ANTENNA NEAR POWER LINES IS DANGEROUS 

 
 
 
 
 

Warning

:

 Do not locate the antenna near overhead power lines or other electric light or power 

circuits, or where it can come into contact with such circuits.  When installing the antenna, take 
extreme care not to come into contact with such circuits, because they may cause serious injury or 
death.  
 
 

Overhead Power Line Safety 

 
Before you begin working, check carefully for overhead power lines in the area you will be 
working.  Don't assume that wires are telephone or cable lines: check with your electric utility for 
advice. Although overhead power lines may appear to be insulated, often these coverings are 
intended only to protect metal wires from weather conditions and may not protect you from electric 
shock 
 
Keep your distance! Remember the 10-foot rule:  When carrying and using ladders and other long 
tools, keep them at least 10 feet away from all overhead lines - including any lines from the power 
pole to your home. 
 
 

Installation 

 

Site Selection 

 
Select a mounting location clear from power lines and structures by a minimum of 78 feet (68 plus 
10 for the 10 foot safety rule). 

Consider overhead power lines, utility cables and wires

. The 

vertical should mounted away from local noise sources or other metallic objects which can re-
radiate noise and affect the tuning, radiation pattern and SWR. Determine the direction you want the 
antenna to tilt down and make sure there is adequate clearance. There should also be a clear 
diameter of at least 70 feet from the antenna for the guying and radial systems that will extend away 
from the antenna. 
 
 

Radial System 

 
Using an optional patented 

DXE-RADP-3

 

Radial Plate greatly simplifies mounting radial wires in a 

vertical installation. The 

DXE-RADP-3

 stainless steel Radial Plate contains enough stainless 

hardware sets to attach 20 radials. Additional 20 set radial connection hardware kits 

DXE-RADP-

HW1K

 are available from DX Engineering.
