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.
