THE CAUSES OF INTERFERENCE 
Incorporated in your TV set is the most up-to-date technology to eliminate 
interference. Local radiation however, can create disturbances which in turn, can 
noticeably affect the picture. Proper installation and a good antenna are your best 
safeguards against these disturbances. 
Interference 
Moving ripples across the screen are caused by nearby transmitting or receiving shortwave radio 
equipment. 
Diathermy 
Herringbone pattern and partial picture loss can result from the operation of diathermy equipment 
from a nearby medical center or hospital. 
Snow 
Weak TV signals from long distant stations result in an unsteady picture and give the effect of 
falling snow. An antenna adjustment or antenna amplifier may be needed. 
Ghost 
Multiple images caused by TV signals reflected back from surrounding buildings, hills, aircraft, etc. 
are minimized by proper antenna positioning. 
Car Ignition 
Nearby cars and electrical motors can cause small streaks across the picture or make the picture 
roll.
