WARNING! 

 

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. 
 

Fiberglass Information 

The mast sections in this kit are fiberglass. Take normal precautions when handling any fiberglass 
material. 

There may be fiberglass dust, slivers or particles present when the fiberglass parts 

were manufactured.

 The use of typical fiberglass handling safety gear, (gloves, dust mask, eye 

shield, clothing, etc.) when handling and working with fiberglass, is recommended. Use a damp rag 
to wipe the parts. 

Do not

 use compressed air to clean fiberglass parts. Measures can be taken to 

reduce exposure after a person has come in contact with fiberglass. Eyes should be flushed with 
water and any area of exposed skin should be washed with soap and warm water to remove fibers. 
Clothing worn while working with fiberglass should be removed and washed separately from other 
clothing. The washing machine should be rinsed thoroughly after the exposed clothing has been 
washed. Check with your local or state safety and/or environmental agencies for more detailed 
precautions.
