• Reorient or relocate the receiving antenna.  

•  Increase  the  separation  between  the  equipment  and 
receiver.  

•  Connect  the  equipment  into  an  outlet  on  a  circuit

ANTENNA AND CABLE CONNECTION

:  

•  If  an  outside  antenna  or  cable  system  is  connected  to 
the  equipment,  be  sure  the  antenna  or  cable  system  is 
grounded  in  order  to  provide  protection  against  built-up 
static  charges  and  voltage  surges.  Article  810  of  the 
National Electrical Code, ANSI/NFPA 70 (in Canada, Part 
1  of  the  Canadian  Electrical  Code)  provides  information 
regarding  proper  grounding  of  the  mast  and  supporting 
structure,  grounding  of  the  lead-in  wire  to  an  antenna 
discharge  unit,  size  of  grounding  conductors,  location  of 
antenna  discharge  unit,  connection  to  grounding 
electrodes and requirements for the grounding electrode.  

•  Outside  antenna  system  should  be  located  well  away 
from  power  lines,  electric  light  or  power  circuits  and 
where  it  will  never  come  into  contact  with  these  power 
sources  if  it  should  happen  to  fall.  When  installing  an 
outside  antenna,  extreme  care  should  be  taken  to  avoid 
touching  power  lines,  circuits  or  other  power  sources  as 

this  could  be  fatal.  Because  of  the  hazards  involved, 
antenna installation should be left to a professional.
