Causes of interference
Incorporated in your TV receiver are the most up-to-date devices to eliminate interference. Local radiation however, can create disturbances, which visibly affect your picture. Proper installations, a good aerial are your best safeguards against these disturbances.
• RF INTERFERENCE: Moving ripples across the screen are caused by nearby transmitting or
receiving short-wave radio equipment.
• DIATHERMY: Herringbone pattern and partial picture loss can result from the operation of
diathermy equipment from a nearby doctor’s surgery or hospital.
• SNOW: Weak TV signals from long distant stations result in an instead picture and give the
effect of falling snow. An antenna adjustment or antenna amplifier may be needed.
• GHOST: Multiple image, caused by TV signals reflected back from surrounding buildings,
hills, aircraft, etc. is minimized by correct aerial positioning.
• CAR IGNITION: Nearby cars and electrical motors can cause small streaks across the picture
or make the picture roll.
