  WARNING!  Never  mount  this,  or  any  other  antenna  near  power  lines  or  utility  wires!  Any  materials: 

ladders,  ropes,  or  feedlines  that  contact  power  lines  can  conduct  voltages  that  kill.  Never  trust  insulation  to 
protect you. Stay away from all power lines. 
 

 WARNING! Never operate this antenna where people  could be subjected to high levels of RF exposure, 

especially  above  10  watts  or  above  14  MHz.  Never  use  this  antenna  near  RF  sensitive  medical  devices,  such  as 
pacemakers. 
 

 WARNING! A tuned loop can exhibit several  hundred Volts and concentrated electromagnetic radiation 

when  operating  at  QRP  power  levels  (5-10  W).  At  higher  RF  levels,  several  thousand  volts  will  be  present  at 
resonance! Exercise caution when using this antenna. Operate this antenna at your own risk.
